Matrix Calculations (MATRIX)
Use the MATRIX Mode to perform calculations involving matrices of up to
3 rows by 3 columns. To perform a matrix calculation, you first assign data
to special matrix variables (MatA, MatB, MatC), and then use the variables
in the calculation as shown in the example below.
Example 1: To assign
to MatA and to MatB, and then
perform the following calculations: × (MatA×MatB),
+ (MatA+MatB)
1. Press
(MATRIX) to enter the MATRIX Mode.
2. Press (MatA) (2×2).
• This will display the Matrix Editor for input of the elements of the 2 × 2
matrix you specified for MatA.
(1) "A" stands for "MatA".
3. Input the elements of MatA: 2 1 1 1 .
4. Perform the following key operation:
(MATRIX) (Data) (MatB) (2×2).
• This will display the Matrix Editor for input of the elements of the 2 × 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 (MatA×MatB):
(MATRIX) (MatA) (MATRIX) (MatB) .
•
This will display the MatAns screen with the calculation results.
