MATLAB: Is there a better to multiply matrices with is pattern

Question

I have a 2 x 2 matrix A = [1 2; 3 4] and a 100 x 1 column vector B = [1 2 3 4 5 6 . . . 100]' and I want to multiply matrix A with each 2×1 sub-vector of B.

For example : [1 2; 3 4] * [1 2]

[1 2; 3 4] * [3 4]

[1 2; 3 4] * [5 6]

.

.

.

[1 2; 3 4] * [99 100]

How can I do this efficiently in code and store the results into one column vector?

Answer 1

Just

 C = A * reshape(B, 2, []) ;

will produce a 2x50 C matrix whose columns are the 50 solutions.
