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 significant digit.
# If a matrix calculation result is too large to
fit 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.
