uComplex Number Calculations with a Matrix

Example	To determine the absolute value of a matrix with the following complex
	number elements:
	Matrix D =	–1 + i 1 + i
		1 + i –2 + 2i
	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+bi, 'r∠θ

Note, however, that “'a+bi” 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.

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.
