Matrix Calculations
Before starting matrix calculations, you have to create one
matrix or a maximum of four matrices named A, B, C and D at
one time. The matrix dimension can be up to 4x4.
The matrix calculation results are stored into the MatAns
memory automatically. You can use the matrix MatAns
memory for any subsequent matrix calculations.
Press to exit the matrix creating screen.

DESCRIPTION
MATX ITEM
Example:
Multiple Matrix C = by 2 <Result: >
3 -2
-1 5
6 -4
-2 10
Obtain the Scalar Product of a Matrix
Each position in the matrix is multiplied by a single value, resulting in a
matrix of the same size.
EX #51
Obtain the Determinant of a Matrix
Example:
Obtain the determinant of Matrix C =
<Result: -471>
10 -5 3
-4 9 2
1 7 -3
! An error occurs if you obtain the determinant of a non-square matrix.

MatB =
, MatA x MatB=?
1 2 3
4 5 6
7 8 9
9 8 7
6 5 4
3 2 1
EX #50
! Matrices which will be added, subtracted or multiplied must be the
same size. An error occurs if you try to add, subtract or multiply
matrices whose dimensions are different from each other. For
example, you cannot add or subtract a 2 x 3 to a 2 x 2 matrix.
