– [Matrix] > [MatA] – [Matrix] >
[Matrix Calc] > [Matrix Squared]
– [Matrix] > [MatA] – [Matrix] >
[Matrix Calc] > [Matrix Cubed]
Example 5: To invert MatA (MatA
-1
)
– [Matrix] > [MatA] – [Matrix] >
[Matrix Calc] > [Inverse Matrix]
Note
• Only square matrices (same number of rows and columns) can be inverted. Trying to
invert a matrix that is not square produces an error.
•
A matrix with a determinant of zero cannot be inverted. Trying to invert a matrix with a
determinant of zero produces an error.
• Calculation precision is affected for matrices whose determinant is near zero.
Example 6: To obtain the determinant of MatA (Det(MatA))
