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)
