Compute the 2-norm of the inverse of the 3-by-3 magic square A. Compute the norm of [x y] and simplify the result. Because symbolic scalar variables are assumed to be complex by default, the calls to abs do not simplify. Assume x and y are real, and repeat the calculation.

This command returns the maximum absolute row sum of each matrix. When each page of a multidimensional array contains a vector, you can use pagenorm to calculate vector norms of each page.

Because symbolic scalar variables are assumed to be complex by default, the calls to abs do not simplify. Assume x and y are real, and repeat the calculation. Now, the result is simplified. Remove assumptions on x for further calculations.
