Convolution of to matrices

I'm looking for a way to input these vectors in matlab and get the same answer

Read about conv2.

Answer 1

[Bruno Luong]

Example

t1 = 0:2;
A1 = [0.25 0.5 0.25];
t2 = [0 3 6];
A2 = [0.25 0.5 0.25];

Code for convolution vector Y (t,A) (I don't know what mean "shaper") of two "impulse" signals (t1,A1) and (t2,A2)

A = A1(:).*A2(:).';
[t,~,i] = uniquetol(t1(:)+t2(:)');
A = accumarray(i(:),A(:)).';
t = t.';
Y = [A;t]

Result

Y =

    0.0625    0.1250    0.0625    0.1250    0.2500    0.1250    0.0625    0.1250    0.0625
         0    1.0000    2.0000    3.0000    4.0000    5.0000    6.0000    7.0000    8.0000
