Member Function Documentation

operator=()

template<int D>

CField< D > & Pscf::Prdc::Cuda::CField< D >::operator=

(

const CField< D > &

)

Assignment operator.

If this Field is not allocated, allocates and copies all elements.

If this and the other Field are both allocated, the capacities must be exactly equal. If so, this method copies all elements.

Parameters

other

the RHS CField
