Multiplication of two arrays of different size

I have two arrays of different size. For example, one array is 43008*24 and other one 33792*24. Ho can I multilpy them?

[John D'Errico]

What does multiplying them mean to you? What size result would you expect?

Let's make a smaller, manageable version of what you are asking for. Suppose

A = [2 3; 5 7; 11 13]

A = 3×2

2 3 5 7 11 13

B = [4 6; 8 9; 10 12; 14 15]

B = 4×2

4 6 8 9 10 12 14 15

You want C that somehow equals the product of A and B. What is the result in this case?

If I take transpose of B and then multiply them, then I will get 3*4 matrix.

A = [2 3; 5 7; 11 13];
B = [4 6; 8 9; 10 12; 14 15];

C = A * B.'

C = 3×4

26 43 56 73 62 103 134 175 122 205 266 349
