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.

MatAns → Mat

In the above,

is any variable name A through Z. The above does not affect the contents of

Matrix Answer Memory.
