Homework Statement
Let S = { u1, u2, u3} be an orthogonal set of nonzero vectors in R3. Define (3 x 3) matrix A by A = [u1, u2, u3]. Show that A is nonsingular and A'A (' is transpose) is a diagonal matrix. Calculate the diagonal matrix using the given orthogonal vectors: u1 = [1 1 1]'; u2 = [-1 0 1]'; u3 = [-1 2 -1]'

The Attempt at a Solution
I think my IQ drops by the minute, thereof a stupid question... what does it mean to "define" the matrix? Do I just create the matrix from the given set of vectors??
