hi !
i want to convolute a vector a=[a1 a2 a3 .....an] with the vectors in this matrix
b=[B1 B2 B3....Bn]. B are vectors.
is there any smart method to make this without loops?
C=[conv(a,B1) conv(a,B2)....conv(a,Bn)]
thank you

out = conv2(b, a);

yes! you can do the following:
y=conv(a, b)

No, this will not work.
Notice in the original question that B is a matrix -- each is a vector and the result is a 2D array.
conv() cannot be used with a matrix, only with vectors.
You need to use conv2() instead, as shown by Image Analyst.
