Casio FX-9750G, FX-9860GII IMatrix Calculations, STo display the matrix commands, STo assign the contents of a matrix column to a list, Mat, Det, Trn, Ref, Iden, Rref, Example, RUN • MAT

•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 Α)

Augment (Mat Α, Mat Β) μ Mat Γ

In the above, Α, Β, and Γ are any variable names A through Z, and n is any value. The above does not affect the contents of Matrix Answer Memory.

STo assign the contents of a matrix column to a list [OPTN]-[MAT]-[MμL]

Use the following format with the MatμList command to specify a column and a list.

Mat μ List (Mat X, m) μ 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)(MμL)

(Mat)?T(A)A

?*(LIST)(List)@U

(List)@U

IMatrix Calculations [OPTN]-[MAT]

Use the matrix command menu to perform matrix calculation operations.

STo 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.
