##
CONJ

The
CONJ function returns the
complex
conjugate of *
X*
. The complex conjugate of the real-imaginary pair (*
x, y*
) is (*
x, -y*
). If *
X*
is not complex, a complex-valued copy of *
X*
is used.

###
Calling Sequence

Result = CONJ(*
X*
)

###
Arguments

####
X

The value for which the complex conjugate is desired. If *
X*
is an array, the result has the same structure, with each element containing the complex conjugate of the corresponding element of *
X*
.

###
Example

Print the conjugate of the complex pair (4.0, 5.0) by entering:

PRINT, CONJ(COMPLEX(4.0, 5.0))

IDL prints:

( 4.00000, -5.00000)
