Circular convolution with single element array showing error

Hi ,

When I try to do circular convolution of two vectors,it shows error when one of the vectors is single element.

How do I rectify the problem? The error message is shown below:

>> s=[1];
>> q=[1 2];
>> res=cconv(s,q)

Error

Error using  .* Matrix dimensions must agree.
Error in cconv (line 46)
c = ifft(fft(datawrap(a,N),N).*fft(datawrap(b,N),N));

On my R2018b your code outputs

res =
     1
     2

I am using version R2015b, I guess that may be the problem.

Thank you for reply
