The number of columns in the left matrix must match the number of rows in the right matrix. || - ||SUBTRACT ||'''Subtract''' will determine the difference of two matrices. The matrix may be subtracted from itself, and the result matrix may be either of the two input matrices. The right matrix is subtracted from the left matrix. || - ||SYMMETRIZE ||'''Symmetrize''' will symmetrize a real square matrix. If the result matrix does not exist at the time of the command, it is created. If the result matrix does exist, all previous information is lost. The result matrix may be the same as the input matrix. || - ||TRANSPOSE ||'''Transpose''' a matrix. If the result matrix does not exist at the time of the command, it is created. If the result matrix does exist, all previous information is lost. The result matrix may be the same as the input matrix, but results in a matrix filled with zero-valued elements. || ||... ||... || ---- @@ -87, +85 @@ == Basic Usage == .. == Basic Matrix Operations == + .. - - '''Not Good....
