Class TempLat::Field

template <typename T, size_t _NDim>

A class which is a classical field on your n-dimensional equisized grid. You use it as a scalar field, a vector component, whatever. Template parameter is your type of floating point precision: float or double. Default: double. More...

Detailed Description

Implements a get method, and is hence suitable for all algebra.

Unit test: ctest -R test-field

@vocab-summary A real scalar field on the lattice, and the type that owns the memory. Assigning to it evaluates an expression across every site; passing it into one makes it a leaf. @vocab-signature Field<T, NDim> phi("phi", toolBox);
