I have a statement as follows: wc = FWT_PO(x_use,4,QMF) where QMF is the name of a MATLAB function (QMF.m, the Quadrature Mirror Filter function). x_use is an array. The function FWT_PO is just regular MATLAB statements. Problem is that control immediately goes to QMF.m whereupon it bombs out with a "not enough input arguments" error message. Do not understand this form of function call line, cannot find it described in the MATLAB "Help", & thus do not understand cause of the error or how to fix.

I downloaded the MS visual C++ 2008 Express Edition and the SDK as detailed in http://www.mathworks.com/support/solutions/en/data/1-6IJJ3L/?solution=1-6IJJ3L My embedded function didnt work at the beginning because I did "mex -setup" before I installed my SDK. But after I installed the SDK, I ran "mex -setup" in Matlab once again and choose the MS visual C++2008 as my compiler. Then, my embedded matlab function worked. Thanks to the contribution from above! ...

I am trying to create an exe from a matlab function which doubles the number you give it. matlab function: test.m function [output] = test (number) %return double the input number output = 2*number; disp(output); run matlab compiler at command line with: mcc -mv test.m with the resulting exe: test.exe However when I run it at DOS prompt: test 1 I am returned a value of 98. I thought that maybe this was some octal description of the output, but 98 oct is not 2 decimal. Some other results it returned: C:\Documents and Settings\alex\Desktop\lighttrans\Frank Work \test...

I am writing some OOP code in Matlab and I wonder if there is any way to specific a function from the Matlab built-in class. The reason why I want to do this is because I want to be able to use some of the Matlab built-in function names (such as "mean" and "kurtosis") as property names of my class and use the corresponding builtin function to compute these property values. To illustrate my problem, I want to be able to do something like this: function value = get.mean( obj ) value = MatlabClass.mean( obj.values ) ; end Thanks for reading. Perhaps t...

Hello all: Given a masked region and dimension of an image, Matlab can return a image with indicated width and height and display masked region as a image.

Hi guys. I really apologize for asking this question, since I'm sure it is either basic or not possible, but I have been reading through the documentation and can't seem to figure this out, since the examples look like they just send and receive variables from the Java methods. Could anyone give me a short example of how to call a method from a Java object that causes some sort of action to be performed in MATLAB? For example, I would like to: 1) make a new object of MyClass from MATLAB called MyObject. 2) run MyObject.DoSomethingInMatlab() 3) have a statement in DoSomethingInMatlab...

I have the following problem. I have created a simple Matlab GUI (for our purposes it can just be considered a Matlab function) which gathers some parameters and then invokes a perl script that in turn calls other perl and Matlab scripts to perform various calculations. If instead of using the Matlab GUI, I run the perl command from the unix prompt, the flow runs and concludes correctly. BUT if I invoke the flow from the Matlab GUI (function), then it runs correctly by calling various other perl and Matlab scripts, but then when it reaches the third Matlab function call, it consistently stalls...

For my project, I need to have a client program (MATLAB executable) talking to a server program (also MATLAB executable) to query data. Is there any easy way to accomplish that?

Does anyone know if there is a way to interrupt a long-running MATLAB function in such a way that one can execute a separate set of commands in a "catch"-type environment? Basically, I'd like to combine Cntl-C with error trapping, so that Cntl-C executes a catch block (i.e., try-catch-end), since it doesn't occur naturally. I have done something similar to this in a GUI environment, but in this case, it is in batch mode.

Hello, Is there any limitation to run Matlab from Matlab, as a system command, on Linux platforms ? I tried to start Matlab, both using the ! syntax (!matlab&) or the system command (system('matlab&')), the Matlab splash screen appears, but the new Matlab session closes rapidly . When I do the same with a script of mine (system('matlab -r "myscript"&')), my script is being executed, but Matlab finally crashes . If I remove the &, it works well, but the first Matlab session is blocked till I close the second one . I run Matlab on a Linux 64bits pla...

I am new to using mcc, mbuild, and mex - I'm attempting to use these to compile a function in matlab into a dll or exe so that I can re-use it in Matlab just as if it was still an m file. First, I wanted to verify that the code works, and I have received a demo license of the Matlab Compiler to test. As a simple example I've written the following function: function [output_var] = this_is_a_test(input_var) output_var = input_var*2; return I've tried multiple combinations of the mcc call in attempts to compile this function, some compile, some don't. First I tried this call: m...

Hi all, I have two GUIs which were derived from the same original one GUI. Let's say I originally have a GUI A, I have copied this GUI and modified it and renamed to two new GUIs: A1 and A2. I have stored the two GUI under two different directories: C:\my projects\working\A1 C:\my projects\working\A2 The two GUIs consist of the same functions but in different directories and fulfill different functionalities... but if I do: which an_example_of_a_function, it always points to C:\my projects\working\A1, and the A2 version has been shadowed... How can I dynamically load the two pa...

Hello, I am a new user of Matlab and I just installed R2007b with 50 toolboxes.

How to use new functions of new Matlab version in the old version of Matlab? Maybe it is not a good question but the situation is that I have got a MatlabR2008b on my laptop but the PCs of the university got only MatlabR2007b. I just want to use one particular function in the MatlabR2008b on the university machine. How can I do that? Just copy the toolbox? Or can I build the function as a .dll? Thanks! p.s: Of course I can not persuade the university to buy one MatlabR2008... I am also not the administrator; thus, I can not setup my MatlabR2008 on the university machine even I got th...
