I have two functions;
f[x_] = (1/k) Exp[-x/k] ; g[x_] = (1/p) Exp[-x/p] ;
How I can convolve them?
In Mathematica for convolving two functions we have this function:
Convolve[f, g, x, ??]
But I don't know how to do the convolution with the above function for my case.
before I ask this question I searched in detail but I didn't find what I need.
Note: the solution of the above functions is:
(1/k) Exp[-x/k] * (1/p) Exp[-x/p] = (1/(k-p)) ( Exp[-x/k] - Exp[-x/p] )
where * is the convolution.
So, how to do this convolution in Mathematica?
