plot graphs above each other
Hello, I have different signals witch, I would like to compare. The signals have roughly the same shape, but a different distribution. I want to plot the signals above each other. All peaks should be aligned with the peaks of the other graphs as good as possible. If I have managed this, I must be able to calc... 16 Jun 2010 06:40

Problems about using the fourier() and ifourier() to get the variables convolution
Hey： Everybody, I got a problem about the variables convolution, the condition is as follow: a(x),b(x),c(x) are all the functions in the space domain, assume that c(x) = conv(a(x),b(x)), x is symbolic. In MATLAB, I want to use the method of "ifourier(fourier(a)*fourier(b))" to get c(x); I... 16 Jun 2010 05:35

Solving and plotting
Hi all, I know this is a simple question, but I am not well-versed in MATLAB and just need to solve a (complicated) equation and then plot it. The equation is: 44.0526*exp(-2*k*t)=-(log(1-(A/(B*Qm-C)))+A/(B*Qm-C)+X*(A/(B*Qm-C))^2)/((A/(B*Qm-C))^(1/3)-(A/(B*Qm-C))) where A, B, C, k and X are all constants for ... 16 Jun 2010 13:15

How to generate a random strongly connected graph??
Hi, guys! I have some interesting problem now: How to generate a random strongly connected graph in matlab? Or how to generate its random adjacent matrix (That is a random non-singular matrix with rank N-1)? I want to use this in my simmulation work on cognitive radio network. I have searched it in google, but no a... 16 Jun 2010 04:31
