Matrix Calculation Precautions
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.
