uTo assign the contents of a matrix column to a list [OPTN]-[MAT]-[Mat→Lst]

Use the following format with the Mat→List command to specify a column and a list. Mat→List (Mat X, 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

K2(MAT)2(Mat→Lst)

1(Mat)av(A),c)

aK1(LIST)1(List)bw

1(List)bw

kMatrix Calculations [OPTN]-[MAT]

Use the matrix command menu to perform matrix calculation operations.

uTo display the matrix commands

1. From the Main Menu, enter the Run-Matrixmode.

2. Press K to display the option menu.

3. Press 2(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)}

•{Identity} ... {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.
