How to do matrix multiplication on Casio 115ES?
Hello First you must set Matrix calculation [MODE][6:Matrix]. Then By entering one of the numbers [1:MatA] or [2:Matb] or [3:MatC] you get to choose the dimensions of the matrix (mxn]. Once finished entering the matrix you clear the screen. The operations on matrices are available by pressing [Shift][Matrix] [1:Dim] to change the dimension of a matrix (in fact redefining the matrix) [2:Data] enter values in a matrix [3:MatA] access Matrix A [4:Matb] access Matrix B [5:MatC] access matrix C [6:MatAns] access the Answer Matrix (the last matrix calculated) [7:det] Calculate the determinant of a matrix already defined [8:Trn] The transpose of a matrix already defined To add matrices MatA+MatB To subtract MatA-MatB To multiply MatAxMatB To raise a matrixe to a power 2 [x2], cube [x3] To obtain inverse of MatA already defined MatA[x-1] [x-1] is the x to the power -1 key Dimensions of matrices involved in operations must match (see you textbook for the rules) Read the appendix to your user ma
