simulink break point
i have a simulink file called sim.mdl it uses fonc.m for some of the calculations. when i put a breakpoint to fonc.m file, sim.mdl file doesn't care the breakpoint, and works as there is no break point. how can i handle this? thank you ... 26 Feb 2010 05:14

Convolution?
Hi, I tried the code above but with slightly different gauss and lorentzian profiles as given by the theory. However when I do convolution between the two the line is shifted to other wavenumbers compared to the code above. Why does it do this and how can I stop it? I want it to appear where the other two lines (ga... 22 Feb 2010 05:14

subpixel image translation
Hi, I have a set of radiographic images of an object taken at different angles. 180images to be precise (2 deg step). I know that the center of rotation did not match with the cg of the specimen accurately and therefore i want to shift each of the images with certain pixel value which is not essentially integer but a ... 25 Feb 2010 02:36

error management in optimization
Can anyone tell me how I could get the parameters vector that caused the objective function to return a complex number or a NaN, with fmincon or fminunc? I work with R2008b and R2009a. Thanks in advance. ... 22 Feb 2010 08:30

radial basis network with multiquadric function
Hello, I want to create a radial basis network with a multiquadric function. I changed the function on the radbas.m code, but I also want to vary a parameter of this multiquadric function aiming to find a best configuration. I tried to pass a second parameter to my radbas function using the parameter 'fp', but it is... 22 Feb 2010 05:14

RGB 2D slice in a 3D plot
Hello, I made a program in which I segmented a certain RGB object from a picture. In the image, only the RGB pixels are shown and the surrounding pixels I gave a zero-value. Now I want to plot only the RGB slice in a 3D plot, without the surrounding pixels. So that the surrounding is transparant. Does anyone hav... 23 Feb 2010 03:33

Speed change of SUM
Dear readers! I've done some comparisons between Matlab's SUM and a C-Mex function. Now I'm confused about this: Matlab 2009a, single threaded (1.5 GHz Pentium-M): x = rand(88999, 1); tic; for i = 1:1000; v = sum(x); clear('v'); end 0.22 sec x = rand(89000, 1); tic; for i = 1:1000; v = sum(x); c... 27 Feb 2010 07:43

Pass large matrices accross matlab functions
Hi I need to pass a few large matrices (50,000x3 elements each) across my matlab functions. 1) I dont want to pass copies of them as variables as my functions are called about 10000 times and I dont want to fragment memory 2) I dont want to read from disk within each function call as it will slow down my code ... 22 Feb 2010 05:14
