The REAL_PART function returns the real part of its complex-valued argument.
Examples
The following example demonstrates how you can use REAL_PART to obtain the real parts of an array of complex variables.
cValues = COMPLEX([1, 2, 3],[4, 5, 6])
PRINT, REAL_PART(cValues)
IDL prints:
1.00000 2.00000 3.00000
Syntax
Result = REAL_PART(Z)
Return Value
If the complex-valued argument is double-precision, the result will be double-precision, otherwise the result will be single-precision floating-point. If the argument is not complex, then the result will be double-precision if the argument is double-precision, otherwise the result will be single-precision.
Arguments
Z
A scalar or array for which the real part is desired. Z may be of any numeric type.
