I want to write a code for convolution of two functions (e.g., lorentzian and exponential) in Matlab. I am familiar with basics of Matlab, but not familiar with convolution of the functions.
Convolutions are easy, look up Bracewell's "The Fourier transform and its Applications". In Matlab, the function for convolution is conv(a,b).
Dear, For Convolution in Matlab their is a predefined function for the same. Try to follow matlab latest book by Mc Graw hill for the same
Best wishes,
This may be helpfull

First generate your lorentzian and laplacian sequences, namely f1 and f2, within a desired range. After that, use y=conv(f1,f2) to convolve the sequences, obtaining a sequence y with a larger range length(f1)+length(f2)-1. To represent the result, you only have to be careful of the sample corresponding to zero time. As my colleges have said, there are lots of useful tutorials around the web.
Make sure you know how to read and interpret the result. I suggest you start by using a couple of very short sequences (say, N=4), so you can do it by hand and compare the result with MATLAB's.
Try google ffor convolution of two function matlab....
