discrete-time signal
hi, please , can anybody help me to write code and plot this signal? Define the discrete-time signal x(n) = n u(n) in a vector in the range 0 ≤ n ≤ 10 and plot the signal. thanks in advance ... 21 Mar 2010 19:42

image processing- correlation map
Hey, I have a matrix which contains "grades" of correlation between patches. the range of the grades is [o 1]. how can I create a correlation map (or heat map) that shows in the optimal way the distribution of the grades received. I will appreciate any help. thanking you in advance! ... 20 Mar 2010 16:36

DSP
I want to write a program in matlab to simulate a discrete feed forward circuit with 2 coefficients and then 3 coefficients. The first coefficient represents zero delay. The circuit needs to accept any size input. I am new to signal processing using matlab, I would appreciate any help and information that will put m... 21 Mar 2010 09:23

Problems using fmincon
I want to perform parametrized function optimization with constraints using fmincon. I wrote appropriate nested function, that is being optimized, defined constraints and so on. However I run into a problem: optimization stops in the second iteration (Optimization terminated: first-order optimality measure less than op... 22 Mar 2010 14:12

Fsolve
Hi all, i am trying to solve a system of linear/nonlinear equations using fsolve command in matlab. But i am getting some undesirable results. First of all, kindly look at the code. function F=myfun(X,c1) a=X(1); b=X(2); c=X(3); d=X(4); e=X(5); f=X(6); g=X(7); p=X(8); F(1)=a+b+d+g-c1(4); F(2)=c1(... 29 Mar 2010 20:18

Image Rotation
Hi All, one more question) How can i rotate an image around user defined point. Not around its central point, like it possible to do with "imrotate"? Thanks! ... 20 Mar 2010 04:06

Fingertip detection from edge detected hand image.
I'm working on a dynamic gesture recognition algorithm. I'm trying to detect zooming in/out gestures (like the pinch gestures you do on an iPhone). I'm at a stage where the edge of the hand is perfectly detected. The detected hand in one image frame looks like this. http://img715.imageshack.us/img715/867/56205285.jp... 20 Mar 2010 07:23
