SignalProcessing[Conjugate] - compute the element-wise complex conjugate of an array of samples

SignalProcessing[ConjugateFlip] - compute the element-wise complex conjugate of an array of samples, in reverse order

Calling Sequence

Conjugate(A)

ConjugateFlip(A)

Parameters

A

-

Array of complex numeric values; the signal

Description

• 

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.

Thread Safety

• 

The SignalProcessing[Conjugate] and SignalProcessing[ConjugateFlip] commands are thread-safe as of Maple 17.

• 

For more information on thread safety, see index/threadsafe.
