MATLAB: Numerical solution for convolution integral

convolutiondouble integral

Hi, I need to solve numerically the attached double integral, where x1 and x2 are variables, a is constant. x1 comprises the boundary of the first integration.

Can someone suggest how to do this?

Best Regards,

a=...;
L=...;
fun=@(x,y)(0.5*x.^3+x.^2).*exp(-x/a).*(0.5*y.^3+y.^2);
upper_y=@(x)x;
q=integral2(fun,0,L,0,upper_y);

Best wishes

Torsten.

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.

Convolution of time domain signals is the same as multiplication of frequency domain signals. You cannot simply multiple Pxx and H since they have different sizes. You could take the ifft of both, conv and then take the fft of the result. Better would be to use W from pwelch instead of w in calculating H (you need to adjust for the sampling rate).
