#### MATLAB Assignment

```I have a problem with my matlab assignment.
This is the question.

1. Using your knowledge of vector operations determine the unit normal vector at each pixel in fig. 1. Visualise the unit normal vectors onto fig. 1 to form a pin-cushion image  (fig. 4).

2. Using your knowledge of vectors, calculate the intensity of light as a percentage of the intensity of the light rays at each pixel in fig. 1. Visualise this as a shading model (fig. 5).

We are not supposed to do your homework... We can help with (specific) matlab questions though... So try it and then come and ask when you have a particular problem.

Call Matlab m-file from Matlab Scrip Node
My problem with matlab script node is related to calling function in matlab.&nbsp; I created an m-file function that takes an imput temperature (from DAQ) and defines a material property.&nbsp; My matlab script node doesn't seem to recognize my function.&nbsp; I have placed the function in the folder the vi is currently located, but it doesn't read it.&nbsp; 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, &nbsp; I have pasted my matlab code into the matlab scrip node. &nbsp; In this code, I have called a subfunction that I have created. &nbsp; Example k(n)=k_c(T(n)) where k_c is a subfunction I have created. &nbsp; How do I get my code in the node&nbsp;to sucessfully read the subfunction k_c? &nbsp; &nbsp; &nbsp; 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.&nbsp; My matlab script node is working properly.&nbsp; I had never used the "cd" command in matlab.&nbsp; I always set the working directory when I open the program, and put all the m files into t...

Matlab builder JA: parse java string to matlab cell
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 ...

some problems of codes of MATLAB 7.0 working on MATLAB 6.5
I have used MATLAB for few hours.So I don't know the differences between version 6.5 and 7.0.I want to use some codes of MATLAB 7.0, but they doesn't work in MATLAB 6.5.How to change these codes so that they can work in matlab 6.5.Waiting for your help.

Incompatible of MAT file for Matlab 6.5.1 and Matlab 7.0
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: ??? Error using ==> load Unable to read MAT file D:\MATLAB7\work\results.mat File may be corrupt. How can I solve this problem? Thanks. 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: > > ???

Why can't Fortran-mex files be compiled on matlab V5.3 and run on matlab V6?
Hi, does anyone know why Fortran-mex files can't be compiled on matlab V5.3 and run on matlab V6? For example: if I compile the example-program (shipped with matlab) timestwo.f on matlab version 5.3 (R11) and try to run it on matlab version 6+ (R12 or R13), I get the error message: "Unable to load mex file: E:\timestwo.dll. The specified module could not be found. ??? Invalid MEX-file" Likewise if I compile it on matlab version 6.1 (R12), I get a similar error message if run on matlab version 5.3 (R11). However, if I run it on matlab version 6.5 it works OK. If I try the same experiment with the corresponding example file written in C, timestwo.c, I get no such problems. Why is that? Per A. Hi Per, usually MEX-files need to be compiled with the MATLAB version you want it later to run with. The reason is, that the code links against the current dynamic libraries (DLLs), which may change from version to version. You may have luck that it works (see your example of timestwo.f), but you should never rely on this. Titus "Per A.

HMM with matlab
Hello, I have a training text, each word has a category and a semantic annotation, where the category of the word refers the observation, and semantic annotation of the word refers the state. I used this text to train HMM and so I have calculated the transition matrix as well as the emission matrix. Now I want to applicate HMM on a test text in order to know states (semantic annotation). I want to know which function allows me to generate the appropriate states sequence to the new sequence of observation (category) from the test text. Thank you ...

OpenCL and MATLAB
Hi I was wondering if anyone knew if OpenCL can be easily interfaced with MATLAB. I've been programming CUDA code which i've interfaced with MATLAB via the MEX interface, which, despite having some frustrations with the MEX interface, has been extremely productive, as i can examine results so easily in MATLAB. My research group is now planning a project to produce some GPU computing suites and are opting for OpenCL due to it's vendor-agnostic nature and also it's interoperability between GPUs and multi-core CPU machines. What i would like to know is if OpenCL code can be interfaced with MATLAB via the MEX interface successfully, i havent found anything which suggests either way and i don't yet know anything about OpenCL. Your comments will be greatly appreciated Many thanks Matt HI Matt, I saw your postings on using Matlab with CUDA on a Mac. Do you have a more detailed documentation on how to do this?

MATLAB legends
Hi, All. I'm trying to make a plot in MATLAB that has both a traditional plot and a stem plot. I'm having problems generating the legend, however. Here's what I'm doing. hold off; figure(1); plot(x,y,'r-'); hold on; figure(1); stem(x,y,'b'); legend('line plot','stem plot'); hold off; The problem is that the legend doesn't have the correct markings (color actually). I think this may be a problem with version 7.0 but not prior versions. Any MATLAB 7.0 people out there have the same problem? Any work-arounds would be appreciated (e.g., what properties of the legend control the marking style and color?). Thanks, Matt -- Remove Xs from address to reply via e-mail.
