Matrix Calculation Examples
The following examples use MatA = and MatB =
from Example 1, and MatC =
from Example 2. You can input a matrix variable into a key operation by pressing
(MAT)
(Mat) and then pressing one of the following number keys:
(A),
(B),
(C).
Example 3: 3 × MatA (Matrix scalar multiplication). (Result: )
3
MatA
Example 4: Obtain the determinant of MatA (Det(MatA)).
(MAT)
(Det) MatA
- 1.
Example 5: Obtain the transposition of MatC (Trn(MatC)). (Result: )
(MAT)
(Trn) MatC
Example 6: Obtain the inverse matrix of MatA (MatA-1). (Result: )
Note: You cannot use for this input. Use the
key to input "-1".
MatA
Example 7: Obtain the absolute value of each element of MatB (Abs(MatB)). (Result: )
(Abs) MatB
Example 8: Determine the square and cube of MatA (MatA2, MatA3). (Result: MatA2 = , MatA3 =
)
Note: You cannot use for this input. Use
to specify squaring, and
(x3) to specify cubing.
