Detailed Description

Abstract definition of a matrix operator interface.

Everytime you need to apply a matrix to the ansatzfunction's coefficients in single precision derive a class from OperationMatrixSP.

This is an re-implementation of the standard OperationMatrix for single precision floating point numbers in order to increase support for GPUs.
