convolution of two vector

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

Answer 1

[Image Analyst]

out = conv2(b, a);

Great! Thx!

Answer 2

yes! you can do the following:

y=conv(a, b)

[Walter Roberson]

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.
