Solve Ax=b, assuming A is known and b is known. Name the array "A" (name box) and solution vector "b". Highlight the output area with the correct size as determined: a matrix A with dimensions m x n (m rows, n cols) multiplied by a vector or array x (n x k) will yield a vector or array with dimensions m x k. Select the correct output size for x and type in the formula bar: "=mmult(b, minverse(A))" but DON'T press Enter. INSTEAD...
