Why do "corr(x,y)" and "xcorr(x,y)" give different answers when x and y are simulated discrete samples of radar signals of form a*e^ib, with partially correlated randomized b values?
It would be helpful if you could provide a script showcasing the difference and explain why you think the two should be the same...
