MATLAB: How to apply a convolution kernel to every matrix column

convolutionvectorization

I would like to apply a convolution process with a vector(1,10) to each column of a matrix (10,1000) how could I do that using vectorization ?

First of all, this

      f=8000;
      b=8;

is useless information because it will be rewritten anyway below, unless this information is given to you and you don't fully describe the required task. ASSUMING that your professor wants you to perform convolution of the recorded signal with itself, you can perform this:

[s1,f]=wavread('C:\Users\N\Desktop\family.wav');
s2 = conv(s1(1,:),s1(1,:)); %using all columns from the first row
subplot(2,1,1)
plot(s1(1,:))
subplot(2,1,2)
plot(s2)

Of course, the resulting signal will be nothing like the initial signal.
