copy Function
Copies a C++ AMP object. All synchronous data transfer requirements are met. You can't copy data when running code on an accelerator. The general form of this function is copy(src, dest).

Parameters
_Dest
The object to copy to._DestIter
An output iterator to the beginning position at destination.InputIterator
The type of the input interator.OutputIterator
The type of the output iterator._Rank
The rank of the object to copy from or the object to copy to._Src
To object to copy._SrcFirst
A beginning iterator into the source container._SrcLast
An ending iterator into the source container._Value_type
The data type of the elements that are copied.
Remarks
The copy operation always performs a deep copy.
If the extents of the source and destination objects do not match, a runtime_exception is thrown.
You can copy to array and array_view objects from the following sources:
An array or array_view that has the same rank and element type as the destination array or array_view.
A standard container whose element type is the same as the destination array or array_view. Containers that expose size() and data() members perform more efficiently.
