Hello,
i'm trying to convolute two vectors (one is symbolic):

> syms alfa kr beta

> v1 = [alfa kr beta];
> v2 = [2 1];

> conv(v1,v2)

That should give me:

[2*alfa alfa+2*kr k+2*beta beta],

but i had an error
??? Undefined function or method 'conv2' for input arguments of type 'sym'.

Anyone can give me a tip how to solve this problem?
