u Complex Number Calculations with a Matrix
Example To determine the absolute value of a matrix with the following complex
number elements:
Matrix D =
K6( g) 4(NUMERIC) 1(Abs)
K2(MAT) 1(Mat) as (D) w
• The following complex number functions are supported in matrices.
i , Abs, Arg, Conjg, ReP, ImP, ' a+b i , ' r ∠ θ
Note, however, that “ ' a+b i ” and “ ' r ∠ θ ” cannot be used in the Linear input/output mode.
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.

→ Mat α
In the above,
α is any variable name A through Z. The above does not affect the contents of
Matrix Answer Memory.
