• You can use Matrix Answer Memory to assign the results of the above matrix input and edit operations to a matrix variable. To do so, use the following syntax. Fill (n, Mat A) Augment (Mat A, Mat B) m Mat G In the above, A, B, and G are any variable names A through Z, and n is any value. The above does not affect the contents of Matrix Answer Memory. S To assign the contents of a matrix column to a list [OPTN]-[MAT]-[MmL] Use the following format with the MatmList command to specify a column and a list. Mat m List (Mat X, m) m List n X = matrix name (A through Z) m = column number n = list number Example To assign the contents of column 2 of the following matrix to list 1: 12 Matrix A = 3 4 56 *(MAT)(MmL) (Mat)?T(A)A ?*(LIST)(List)@U (List)@U I Matrix Calculations Use the matrix command menu to perform matrix calculation operations. [OPTN]-[MAT] S To display the matrix commands 1. From the Main Menu, enter the RUN • MAT mode. 2. Press * to display the option menu. 3. Press (MAT) to display the matrix command menu. The following describes only the matrix commands that are used for matrix arithmetic operations. • {Mat} ... {Mat command (matrix specification)} • {Det} ... {Det command (determinant command)} • {Trn} ... {Trn command (transpose matrix command)} • {Iden} ... {Identity command (identity matrix input)} • {Ref} ... {Ref command (row echelon form command)} • {Rref} ... {Rref command (reduced row echelon form command)} All of the following examples assume that matrix data is already stored in memory. 2-44
