MATLAB: Easy convolution of multiple vectors

convolutioneasyfastMATLABmultiplevectors

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')
