Why did i receive the error "Subscripted assignment dimension mismatch"?

I created these matrix: A(1x4), B(4x4). But in editor tab when i was creating a function which is multiplied those matrixs and check it, i've got "Subscripted assignment dimension mismatch." error. Why? And how can i solve it?

It will work. You check the dimensions of your matrices. Remember the matrix multiplication rule: Matrices of order mXn, nXp can ve multiplied.

>> A = rand(1,4)

A =

    0.4387    0.3816    0.7655    0.7952

>> B = rand(4,4)

B =

    0.1869    0.7094    0.6551    0.9597
    0.4898    0.7547    0.1626    0.3404
    0.4456    0.2760    0.1190    0.5853
    0.6463    0.6797    0.4984    0.2238

>> A*B

ans =

    1.1239    1.3510    0.8369    1.1770

First pre allocate the A and B matrices. You will get the error message which you got if they are not pre allocated
