MATLAB: How to do convolution of more than 2 signals? I keep on getting errors

convolutionMATLABsignals

I keep on getting errors like this : "Error using conv (line 35) SHAPE must be 'full', 'same', or 'valid'.

Error in mp2no3 (line 25) orig1 = conv(x1est,x2est,x3est);"

conv only accepts two signal at a time. you can not pass it three signal.

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.
