of the elements of the 2 σ 2 matrix you

 

 

 

 

specified for MatA.

 

 

 

 

 

 

“A” stands for “MatA”.

3.Input the elements of MatA: 2 1 1 1 .

4.Perform the following key operation: (MATRIX)(Data) (MatB)(2σ2).

This will display the Matrix Editor for input of the elements of the 2 σ 2 matrix you specified for MatB.

5.Input the elements of MatB: 2  1  1 2 .

6.Press  to advance to the calculation screen, and perform the first

calculation (MatAσMatB): (MATRIX)(MatA)

Whenever the result of a calculation executed in the MATRIX Mode is a matrix, the MatAns screen will appear with the result. The result also will be assigned to a variable named “MatAns”.

The MatAns variable can be used in calculations as described below.

To insert the MatAns variable into a calculation, perform the following key operation: (MATRIX)(MatAns).

Pressing any one of the following keys while the MatAns screen is

displayed will switch automatically to the calculation screen: , , , , , 7, 7(x3). The calculation screen will show the MatAns variable followed by the operator or function for the key you pressed.

Assigning and Editing Matrix Variable Data

Important: The following operations are not supported by the Matrix Editor: 6, 6(M–), =(STO). Pol, Rec, and multi-statements also cannot be input with the Matrix Editor.

To assign new data to a matrix variable:

1.Press (MATRIX)(Dim), and then, on the menu that appears, select the matrix variable to which you want to assign data.

2.On the next menu that appears, select dimension (mσn).
