uDetermining 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

#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.
