Detailed Description

template<typename T, bool useexint = false>
class CE_SparseMatrixELLT< T, useexint >

An ELL-format sparse matrix for OpenCL. This class is fairly limited; its primary purpose is to initialize with an alread-populated UT_SparseMatrixELL, then call its solveConjugateGradient function to solve a linear system using OpenCL.
