Easy convolution of multiple vectors

For the convolution of three vectors I'm doing:

A = [1 2];
B = [3 4];
C = [5 6];
res_aux = conv(A,B);
res = conv(res_aux,C);

Is there an easier way? Something like: res = multiconv({A,B,C})

An alternative would be using cellfun but it's slower.

Here's an fft-based approach

   data=[1 2;3 4;5 6].';
   n=(size(data,1)-1)*size(data,2)+1;

   result = ifft(prod(fft(data,n),2),'symmetric')

Thank you Matt!

I had read about using fft to solve this but I couldn't understand how. Your comment was of great help.

I'm marking this as answered. Once again, thank you!

OK. I'm not sure it's faster/more efficient than a plain for-loop, though. It involves complex-valued arithmetic and probably about 4 times more memory consumption.
