- Fill in the blanks. To encode a message, create an invertible matrix A and multiply the row matrices by A (on the right) to obtain the row matrices.arrow_forwardTrue or false? det(A) is defined only for a square matrix A.arrow_forwardProof Let A be an nn square matrix. Prove that the row vectors of A are linearly dependent if and only if the column vectors of A are linearly dependent.arrow_forward
