SComplex 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
	*(E)(NUM)(Abs)
	*(MAT)(Mat)?Q(D)U

•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 π1 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 μ Mat Α

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

9.Metric Conversion Calculations

You can convert values from one unit of measurement to another. Measurement units are classified according to the following 11 categories. The indicators in the “Display Name” column show the text that appears in the calculator’s function menu.

Display Name	Category	Display Name	Category	Display Name	Category
LENG	Length	TMPR	Temperature	PRES	Pressure
AREA	Area	VELO	Velocity	ENGY	Energy/Work
VLUM	Volume	MASS	Mass	PWR	Power
TIME	Time	FORC	Force/Weight
