The MATLAB commands provided are creating two matrices A and B.

1. `A = eye(2,2);` This command creates a 2x2 identity matrix, A. An identity matrix is a square matrix in which all the elements of the principal diagonal are ones and all other elements are zeros. So, matrix A will look like this:

A = [1 0;
0 1]

2. `B = [ A(:,1) A(:,2)];` This command creates a new matrix B by concatenating the columns of matrix A. `A(:,1)` means all rows in the first column of A and `A(:,2)` means all rows in the second column of A.

So, the matrix B will look exactly the same as A because you are just reassembling the columns of A into B. Therefore, B will be:

B = [1 0;
0 1]
