Property Real As Variant

Stores the real part of a complex array (read/write). The Real property is the

default property of the

MWComplex class. The value of this property can be any

type coercible to a

Variant, as well as object types, with the restriction that the

underlying array must resolve to a numeric matrix (no cell data allowed). Valid

Visual Basic numeric types for complex arrays include

Byte, Integer, Long,

Single, Double, Currency, and Variant/vbDecimal.

Property Imag As Variant

Stores the imaginary part of a complex array (read/write). The Imag property

is optional and can be

Empty for a pure real array. If the Imag property is

nonempty and the size and type of the underlying array do not match the size

and type of the

Real property’s array, an error results when the object is used

in a method call.

Example. The following Visual Basic code creates a complex array with the

following entries:

x = [ 1+i 1+2i

2+i 2+2i ]

Sub foo()

Dim x As MWComplex

Dim rval(1 To 2, 1 To 2) As Double

Dim ival(1 To 2, 1 To 2) As Double

On Error Goto Handle_Error

For I = 1 To 2

For J = 1 To 2

rval(I,J) = I

ival(I,J) = J

Set x = new MWComplex

x.Real = rval

x.Imag = ival

Exit Sub

Handle_Error:

1 2 ... 163 164 165 166 167 168 169 170 171 172 173 ... 181 182
