conv() will never be able to process cell arrays .

You need to use

ab = conv(a{u,1}, b{v,})

[Robert Redinbo]

ab = conv(a{u,1}, b{v,1})

This give me

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);
