Hi Everyone,

Suppose I have a matrix A

A = [2 3 1;1 5 0]

And another matrix B

B = [2 1 3;2 1 3]

Now I wish to create a matrix C, which looks like this

C = [3 2 1;5 1 0]

Notice that:

The first line, first column of C contains that value in line one of A, corresponding to the 1 found in the first line of B.

The first line, second column of C contains that value in line one of A, corresponding to the 2 found in the first line of B.

The first line, third column of C contains that value in line one of A, corresponding to the 3 found in the first line of B.

and so forth for other lines....

What code will create C from A and B?

Kind regards,

Ulrik.
