index of npermutek
Hello =) I'm trying to calculate the (i,j)th element of npermutek(1:4,N) without calculating npermutek(1:4,N). This is because npermutek(1:4,50) is too big to store, yet calculating the (i,j)th element is doable. a=mod(ceil(i/4^j),4); if a==0; a=4; end disp(a) If there is any clever way to speed up this ... 3 May 2010 14:14

Curve fitting MIMO grey-box model using pem and freq. data
Hi, I am attempting to fit a mimo grey box model to some structure vibration frequency response measurements (frd) using idgrey and pem (System Identification tbx), so far with mixed results. I get a warning that initial state estimation is being disabled for some reason, I am not sure why, and I think this may be ... 3 May 2010 19:49

MEX calloc fails
Hi, I have a small MEX file written in C. In side, there is a for loop, and in each iteration the for loop, I allocate a very small amount of memory by doing calloc(6, sizeof(int)) However, in the 9th iteration, calloc already fails, which is impossible, and I'm pretty sure MATLAB can allocate a lot more memory f... 2 May 2010 20:52

Use variables between callbacks
Hi im making a gui, whe i press a button it has a script wich conatins a variable named freq, then i need to use that var in another callback, how can i use that var beacuse it seems it is erased at the end of the buttons callback. is there something like a semi-global variable only to be used and modified insid... 3 May 2010 09:49

Frame Slider in Movie Player
Hi there, I want to add a frame slider in Movie Player (Image Processing Toolbox) so that I can slide back and forth many frames in very short time. But it seems very hard to interact with the Movie Player, for example, to get the handle to the frame being displayed, to add rectangles or lines to the frame or all fr... 2 May 2010 17:34

cognitive radio network
Hello everyone, I am asking the same thing... doing term project on spectrum sensing for CR. Just want some matlab scripts to start... I appreciate if someone could share with me some simple matlab scripts even just for the conventional sensing techniques, such as energy sensing, matched filter, etc etc.. Please e... 21 May 2010 08:23

blur calculation
buddies, if i m generating blurred videos using 2D FIR filter, then how can i classify each video with respect to their amount of blur artifact... manually i know that each blurred videos are different due to change in their gaussian coefficients.. But i need the reverse process.. ie blurred videos are my input.. ... 2 May 2010 20:52

Plot field lines of vector fields using streamslice
I am currently working on a little script to visualize TE and TM modes in rectangular and circular waveguides and cavity resonators. I have 3 vector fields (Hx,Hy,Hz) for the magnetic field and 3 vector fields for the electric field (Ex,Ey,Ez) which makes my problem a 4 dimensional one. I am getting satisfactory resul... 2 May 2010 18:41
