2. Use the Matrix Editor that appears to edit the elements of the
matrix.
• Use the f, c, d, and e 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 MatC =
1
into a key operation by pressing 14(MAT) 3(Mat) and then
pressing one of the following number keys: 1(A), 2(B), 3(C).
3 × MatA (Matrix scalar multiplication). (Result:
