Calculations with Matrices
Arithmetic operations on Matrices
By pressing the
[
OPTN
]
key and
[
F2
]
, the arithmetic operations
for the matrices will be shown, and can be selected, e.g.:
– Determinant of Matrix A:
[
OPTN
] [
F2
] (
MAT
) [
F3
] (
Det
) [
F1
] (
Mat
)
[
ALPHA
] [
X, Ø, T
] (
A
)
– Transpose a Matrix: Trn
– Unit Matrix: Iden
– Dimension of the Matrix: Dim
– Upper triangular form of the Matrix: Ref
– Diagonalisation of the Matrix: Rref
– Exponentiation, e.g. Squaring the Matrix A: Mat A^2
The most recently calculated result is stored in the Matrix
variable Mat Ans.
