S Complex Number Calculations with a Matrix

Example To determine the absolute value of a matrix with the following complex

number elements:

Matrix D =

*(E)(NUM)(Abs)

*(MAT)(Mat)?Q(D)U

• The following complex number functions are supported in matrices.

, Abs, Arg, Conjg, ReP, ImP,

a+b

Note, however, that “

a+b

” and “

” 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

p1 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).

m Mat

In the above,

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.
