Assigns the values of elements from a source range to a destination range.

Parameters

begin

Random access iterator addressing the position of the first element in the source range.

end

Random access iterator addressing the position one past the final element in the source range.

out

Random access iterator addressing the position of the first element in the destination range.

grain

Number of iteration for a reasonable chunk to deal out to a thread. If no value given, the range is subdivided in num_threads() chunks.

X

Source range.

Y

Destination range.

Returns

An output iterator addressing the position that is one past the final element in the destination range

Example

DenseMatrix<ucharImage::index_type>::self M;
gmt::parallel_copy(motion<8,8>(X,Y,32,32),M,X.ncols()/8);
