I have a problem that I cannot see an edit box in the Guide editor, but it appears when I run the GUI. I can't select it do delete it. I see that there is code in the .m file for it but I can't select it in the Guide. I would like to get rid of it entirely. Can you find it's handle while the GUI is running? You might want to try: findobj('style','edit') % If it is labeled with a string, put that in too. I seem to think that GUIDE GUIs have the handles invisible though. If that is the case, when you launch the GUI, do so with an output argument. H = mygui; findobj('parent',H,'style','edit') Once you have the handle, you can delete it.

Does anybody know a good tutorial about how to implement DLLs written in C++ in Matlab? I'm also a beginner in C++, so I practically don't know anything about how to write a DLL (apart from some very basic introduction). I'd be especially interested in how to include functions in the DLL, and how to call them in Matlab. Can be as simple as a standard IO-command. Any help is welcome, so as to get an idea how this works fundamentally. ...

Hi! I am a newbie in case of artificial neural networks. Please answer simple ;-) I need to implement digit classification (OCR) with numbers 0..9 as output and approx. 3800 training images. I also have ~1800 test images. I found the OCR example shipped with Matlab and played with it. It uses a feedforward NN with backpropagation (newff). Here my questions: How can I determinate the optimal number of training images? If I use 3800 it takes some time to train. I played with subsets of 200, 400, 500, 800 images and the results where not linear increasing. Should I "re-train"...

Hi, I have recently started using MATLAB for a DSP and a Communication Theory class. I have some questions about how MATLAB does some things. 1. To plot a graph, say a sinusoid, I always do this: t=0:.1:10; a=sin(t); plot(t,a) What does MATLAB do to generate the data for the points that are not in increments of .1? for example sin(1.13)? Does it interpolate to generate the graph? Is this sinusoid only valid for .1 increments? In fact, a function in MATLAB is inherently discrete, but we use it to model continuous functions (its 'domain' is actually only 101 samples)? 2. I'm having trouble mixing up the indices of the array (1..101 for t matrix) and the actual values (t(1)=0 t(1)=0.1, etc.)I am doing a lot of shifting of functions (such as f(x) = x -> f(x-2) = x-2) and this is messing me up, I usually get the error, "indices must be positive or logicals.." Mathematically, it makes sense to compute f(x(1)-2) for x(1)=1, but it doesn't make sense in MATLAB to ask for f(-1). This brings me to the question of what is a reasonable matrix size for x. -100:.1:100 ? Does it depend on the precision you need? Is there a 'convention' used to model functions? 3. I had a misconception that MATLAB was very close to mathematical notation. In fact, you have to interpret a lot when using it, often going back to the theory to make sure computations make sense. So am I using it the 'right' way. Usually only crunching huge amounts of numbers? I know...

Dear all, I am trying to implement a very simple version of an AM receiver in Matlab but as I am new to this software package I seem to be getting nowhere. So far I have searched the web and Matlab books for examples that would help me to understand how this could be done without much success. I now this is probably a silly thing to ask but could anyone guide me in the right direction, i.e. links to websites, etc. or maybe provide me with a hints. Anything would help really.

Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter? A roundabout way would seem to be to (somehow) Turn the matlab code into C (I think mcc does this), then compile this C code into MEX format and call that. Is there an easier way? I have the MATLAB compiler, so I just need to know what to do with it to get this to work.
