u Raising a Matrix to a Power [OPTN] - [MAT] - [ ]
Example To raise the following matrix to the third power :
Matrix A =
1 2
3 4
K 2 (MAT)1 (Mat)av (A)
M d w
u Determining the Absolute Value, Integer Part, Fraction Part, and
Maximum Integer of a Matrix
[OPTN] - [NUM] - [Abs]/[Frac]/[Int]/[Intg]
Example To determine the absolute value of the following matrix :
Matrix A =
1 –2
–3 4
K 6 (g )4 (NUM)1 (Abs)
K 2 (MAT)1 (Mat)av (A)w

Matrix Calculations
# Determinants and inverse matrices are
subject to error due to dropped digits.
# Matrix operations are performed
individually on each cell, so calculations
may require considerable time to complete.
# The calculation precision of displayed
results for matrix calculations is ± 1 at the
least signifi cant digit.
# If a matrix calculation result is too large
to fi t into Matrix Answer Memory, an error
occurs.
# You can use the following operation to transfer
Matrix Answer Memory contents to another
matrix (or when Matrix Answer Memory
contains a determinant to a variable).
MatAns → Mat
α
In the above,
α
is any variable name A through
Z. The above does not affect the contents of
Matrix Answer Memory.
# For matrix power calculations, calculation is
possible up to a power of 32766.
