I am trying to convolve these two functions.
v = sinc(s/pi)-0.5*(sinc(s/2*pi))^2;
f = sqrt(1-4*s^2);
I keep getting this error:
Error using conv2 Invalid data type. First and second arguments must be numeric or logical.
Error in conv (line 43) c = conv2(a(:),b(:),shape);
Error in CT_ComputerProject_Week8 (line 60) w = conv(v,f,'full');
I'm not sure what to do to fix it. I tried entering a single() or double() function, as this is what I saw to do online, but it did not work either/ maybe I did not enter it in correctly. Help would be much appreciated.

Hi Walter, I have a question about displaying the fv function. Would we use the code
imshow(fv)
If so, I am receiving an error for this.
