To edit the elements of a matrix variable:
1. Press (MAT) (Edit), and then, on the menu that appears,
select the matrix variable you want to edit.
2. Use the Matrix Editor that appears to edit the elements of the matrix.
• Use the , , , and keys to display the element you want to
edit. Input a new value and then press .
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
