Matrix Calculations (MAT) (fx-570MS/
fx-991MS only)
Use the
key to enter the MAT Mode when you want to perform
matrix calculations.
(MAT)
Use the MAT 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.
Note
• Matrix calculations can use up to two levels of the matrix stack. Squaring a matrix,
cubing a matrix, or inverting a matrix uses one stack level. See "Stacks" for more
information.
Example 1: To assign
to MatA and to MatB, and then
perform the following calculations: × (MatA × MatB),
+ (MatA + MatB)
1. Press
(MAT) (Dim) (A).
2. Input the dimensions of MatA: 2 2 .
•
This will display the Matrix Editor for input of the elements of the 2 × 2
matrix you specified for MatA.
(1) Shows the row number and column number of the element.
(Example: MatA
23
indicates row 2, column 3 of MatA.)
3. Input the elements of MatA: 2 1 1 1 .
4. Perform the following key operation: (MAT) (Dim) (B) 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 .
