Conjugate(A)

A
-
Array of complex numeric values; the signal
container : Array, predefined Array for holding results
inplace : truefalse, specifies that output should overwrite input
The Conjugate(A) command computes the element-wise complex conjugate of the elements of the Array A and returns them in another Array.
The ConjugateFlip(A) command computes the element-wise complex conjugate of the elements of the Array A and returns them in another Array in reverse order.
Before the code performing the computation runs, A is converted to datatype complex[8] if it does not have that datatype already. For this reason, it is most efficient if A has this datatype beforehand.
If the container=C option is provided, then the results are put into C and C is returned. With this option, no additional memory is allocated to store the result. The container must be an Array having datatype complex[8] and size equal to that of A.
If the inplace or inplace=true option is provided, then A is overwritten with the results. In this case, the container option is ignored. Furthermore, A must have datatype complex[8]. The inplace option works with the Conjugate(A) command only.
The SignalProcessing[Conjugate] and SignalProcessing[ConjugateFlip] commands are thread-safe as of Maple 17.

The SignalProcessing[Conjugate] and SignalProcessing[ConjugateFlip] commands were introduced in Maple 17.
