Hello, I'm evaluating products for writing my final university thesis. I want to perform image processing algorithms (C-Code compiled for a DSP). I have the feeling that manual programming of this algorithms is no longer state of the art. Instead MDSD (model driven software development) - that means Code Generation - seems to be smarter to me. Unfortunately Mathworks offers no licenses of Matlab Coder (or Simulink Coder etc.) to individual students. And I cannot afford to buy a commercial license (which probably would cost me more than 5.000 EUR/$ / my absolute limit is 1.000 EUR/$). Is there any possibility for me to use MDSD (code generation) for image processing for my university thesis ? Maybe by using cheaper alternatives ? Or by using 3d party software (like target link) ? Or export/import to another product ? Any idea ? (I want to avoid manual coding - like using OpenCV) By the way, does anyone know, why Mathworks hides the MDSD features from students ? It doesn't make sense to me that Mathworks reduces the amount of engineers available on the job market that are capable of handling (serious) Matlab projects. (Microsoft offers the "Visual Studio Express Edition" for free for education and the amount of people on the job market that are experienced in Visual Studio is tremendous.). Thank you, Roelof ...

The Student Version of MATLAB shouldn't need a password -- the bookstore employee was probably thinking of the professional version of MATLAB, which does require a passcode or a license file. Chapter 2 of the Learning MATLAB 6 manual, which should have been included in the box, discusses how to install the Student Version. As long as you follow the instructions in that chapter and have your documentation CD in the drive when you start MATLAB, it should work. There is one issue that you may run into if your machine has a Pentium 4 -- see section 27 of this document for instructions on how to avoid this issue. http://www.mathwo...

Hi , I am profiling code in two different versions of MATLAB (2009a and 2012a). The machine 2012a is installed is newer than the machine with 2009a, and thus, a better CPU. However, when I execute the following: A=magic(10000) A.*A I received two different timing results, the 2009a results (414.0415 seconds) are much lower than 2012a (574.746 seconds). Any suggestion on why this is the case would be greatly appreciated. Also, all other subsecquent code in MATLAB 2012a is much lower than 2009a.

My problem with matlab script node is related to calling function in matlab. I created an m-file function that takes an imput temperature (from DAQ) and defines a material property. My matlab script node doesn't seem to recognize my function. I have placed the function in the folder the vi is currently located, but it doesn't read it. How do I get matlab script node to read the functions I create in matlab? Add the directory to matlab path, or call the .m file with it full name ( D:\..... \myfile.m) Let me clarify, I have pasted my matlab code into the matlab scrip node. In this code, I have called a subfunction that I have created. Example k(n)=k_c(T(n)) where k_c is a subfunction I have created. How do I get my code in the node to sucessfully read the subfunction k_c? As indicated, you need to add the directory where the .m file containing the function resides to the list of paths that are read in. This is your startup.m file. The other option is to do a "cd" command prior to calling your function to change to the directory where the .m file containing the function resides. Thanks for reiterating the information. My matlab script node is working properly. I had never used the "cd" command in matlab. I always set the working directory when I open the program, and put all the m files into t...

Hi all, I'm building a java swing based GUI for my Matlab application. As such, user input is available as text strings, for example "{[0; 0], [3.5 0; 0 2]}" (mean vector and covariance matrix of a 2D Gaussian). The user input will be passed to the compiled matlab method as a MWCellArray. Problem is how do a convert (parse) the above string into a MWCellArray? From its javadoc http://www.mathworks.com/access/helpdesk/help/toolbox/javabuilder/MWArrayAPI/index.html the following method is available: java.lang.String toString() Returns a string representation of this array, but the reverse method is not. Evidently, parsing a string like the one above is a non trivial task and I'm loath to attempt writing one by myself. I would be very thankful if someone can point me to the required parser implementation. Matlab itself is carrying out this task all the time, perhaps it is possible to access Matlab's own parser. Help much appreciated, Ritesh ...

Hi , I have installed MATLAB 7, now if I want to install 6.5 then how to change the version of MATLAB files which are made in version 7, as some files of newer version may not work in older version?

There is NO version number for your m files when you create them? they are just plain text file. But If you create an .m file which runs ok under version 7, and you want this file to run ok under earlier versions (assuming it does not), then you need to make the necessary changes in your m file to make it run under earlier versions (this is sometimes called backporting). But if your m file calls function(s) that are part of Matlab and those functions only exist in version 7 and not in the erarlier version, then you might be out of luck there. I am not sure why you want to do this. The common practice is to go the other way. Any reason why, if you have version 7 you want to use version 6.5? may be if you give the reason it would help to give you a better advice.

I am getting significant differences when using griddata/TriScatteredInterp between different versions of MATLAB. This interpolation is a necessary step in a much larger routine to compute the spectral approximation to a velocity field, and using the griddata/TriScatteredInterp functions in the latest MATLAB release (2012a) produces overall results that do not converge appropriately as the sampling resolution is increased. In contrast, the 2010a results do converge properly. Thus, the newest version of MATLAB appears unusable for me for this problem. The griddata/TriScatteredInterp function is the only MATLAB built-in function I use in my larger routine. I've included a simple routine that samples a velocity field at a discrete number of points, and then tries to interpolate at a new grid staggered from the first. There is no difference (to machine precision) between MATLAB versions for the sampled velocities, however their interpolants differ greatly (the max difference between the interpolants is between 2-4% of the maximum x- and y-velocities). This difference is identical using both the griddata and TriScatteredInterp formulations. It is a shame that the newest release appears to perform so poorly, whereas the older version (2010a) seems to give much more accurate results. Does anyone know why this would be occurring or a workaround to fix it? Is there any way to roll back the current griddata/TriScatteredInterp routines to their 2010a predecessors? I j...

Hi, I am trying to implement PID control in a simple second order servo system using a simulink block diagram. Previously using Matlab7 I could get a PID block, which had a simple options form with coefficient for each of P, I and D. we are now running Matlab 2010b and I have encountered a problem. The PID block is now called PID(s) and the options form is much more complex. It still has fields for inputting coefficients of P, I and D and many more. When using this block the response characteristics are quite different from previously and I cannot tune it to give a desirable response to a simple stepped input. Can anyone shed any light on this? I really just need simple control like I had previously. I am not an expert in control, I am a bio-mechanist who is teaching this to undergraduates. Thanks Oli ...

Hi! I have recently installed Matlab 7.0. I have save my simulation results in .MAT file. However, these MAT files can't be opened using Matlab 6.5.1. I encountered problem as follows: ???

Linda Please see here: <http://tx.technion.ac.il/~perryb/matlab7/mat7.pdf> In short, save again as: The new features and enhancements are described in the "Release notes" of Matlab. A new feature that causes incompatibility with previous versions of Matlab is the new encoding of MAT files. Matlab release 14 writes character and figure data to MAT-files using Unicode encoding by default. Unicode encoded MAT-files are not readable by earlier versions of Matlab. If you intend to load your MAT-files created with Matlab release 14, you must override the Unicode default during the save. You can override the default encoding by using the -v6 switch with save and hgsave: save filename -v6 hgsave filename -v6 Hope it helps Linda wrote: > > > Hi! > > I have recently installed Matlab 7.0. > I have save my simulation results in .MAT file. > However, these MAT files can't be opened using Matlab 6.5.1. > > I encountered problem as follows: > > ???
