A Using the Matrix Editor Screen to Input Matrix Data

1. Press z – {MATRIX}1(EDIT) to display the matrix memory area menu.

A memory area that already contains a matrix will show the dimensions of its matrix (like 2 × 2), while an area that is empty will be indicated by “None”.

2.Use c and f to move the highlighting to the matrix you want to use for data input.

3. Press E.

This displays a screen for specifying the dimensions of the matrix. m is the number of rows, while n is the number of columns.

Note

If you select a memory area that already contains a matrix in step 2, pressing E will display the matrix editor screen so you can edit the matrix. If you want to delete the existing matrix and make a new one with different dimensions, press e or z1(Dim) in place of E in step 3.

4.Specify the dimensions of the matrix you want to create, up to a maximum of 10 rows and 10 columns.

To specify the number of rows, move the highlighting to m, input a value and then press E. This will cause the highlighting to move to n.

Input a value for n to specify the number of columns and then press E.

You can use c and f to move the highlighting between m and n.

5. After inputting the row and column values you want, press E.

• This will display the matrix editor screen.

Cursor

6.On the matrix editor screen, input values into the cells of the matrix.

Use the cursor keys to move the cursor to the cell you want and then input a value. After inputting a value, press E to register it.

7.After inputting all the values you want, press J.

A Using the Value Assignment Command (/) to Input MatrixData

1.On the COMP Mode calculation screen, use the following syntax to input the matrix you want to input into matrix memory.

a11

a12

... a1n

 

 

a21

a22

... a2n

[[a11, a12, ..., a1n][a21, a22, ..., a2n] ... [am1, am2, ..., amn]]

... ... ...

 

am1

am2 ... amn

 

• Inputting 13 24 , for example, can be performed using the following key operation.

Si([)Si([)1,2S6(])

Si([)3,4S6(])S6(])
