MapleSelectRealPart
select the real part of a complex-valued expression in external code

Description
Examples
MapleSelectIndexed(kv, s, n, ind)
MapleSelectImaginaryPart(kv, s)
MapleSelectRealPart(kv, s)
kv
-
kernel handle returned by StartMaple
s
an indexable Maple object
n
length of ind
ind
32-bit integer index array
These functions are part of the OpenMaple interface to Microsoft Visual Basic.
The MapleSelectIndexed function retrieves the element s[ind], where s is a list, set, table, or rtable object. The index is an integer array. To reference s[1,2], set ind(0) = 1, and ind(1) = 2;.
The MapleSelectImaginaryPart function returns the imaginary part of s. The MapleSelectRealPart function returns the real part of s. These commands are equivalent to the Maple Im and Re commands.
Sub TestSelect(ByVal kv As Long)
Dim s, r As Long
Dim ind(2) As Long
s = EvalMapleStatement(kv, "Matrix([[red,yellow],[green,blue]]);")
ind(0) = 1
ind(1) = 2
r = MapleSelectIndexed(kv, s, 2, ind(0))
MapleALGEB_Printf1 kv, "r = %a", r
s = EvalMapleStatement(kv, "1.1+2.2*I;")
r = MapleSelectRealPart(kv, s)
MapleALGEB_Printf1 kv, "re = %a", r
End Sub
