I have a vector A = and a matrix X = , where is a M-dimensional row vector. Does matlab have an operator that directly give me the matrix? (where each row vector in the above matrix X is multiplied by the corresponding part in vector A)

If I understand your question correctly, you should get the desired output using array multiplication -
N=5;
A = (1:N).'
A = 5×1
1 2 3 4 5
X = magic(N)
X = 5×5
17 24 1 8 15 23 5 7 14 16 4 6 13 20 22 10 12 19 21 3 11 18 25 2 9
Z = A.*X
Z = 5×5
17 24 1 8 15 46 10 14 28 32 12 18 39 60 66 40 48 76 84 12 55 90 125 10 45
