CASIO

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.

• MatA
