u Raising a Matrix to a Power [^]
Example To raise the following matrix to the third power:
Matrix A =
K2(MAT) 1(Mat) av(A)
Mdw
• For matrix power calculations, calculation is possible up to a power of 32766.
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 =
K6( g) 4(NUM) 1(Abs)
K2(MAT)1(Mat)av(A)w
• The “Abs” command can be used to obtain the absolute value of a vector element.
u Complex Number Calculations with a Matrix
Example To determine the absolute value of a matrix with the following complex
number elements:
Matrix D =
AK6( g) 4(NUM) 1(Abs)
K2(MAT) 1(Mat) as (D) w
• The following complex number functions are supported in matrices and vectors.
i, Abs, Arg, Conjg, ReP, ImP
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.
