SPARSE_COUNT
Sparse Grids Using a Single Factor

SPARSE_COUNT is a C++ library which contains routines for the analysis and construction of sparse grids in which a fixed family of 1D quadrature rules is used for all spatial dimensions.

By contrast, library MIXED allows different rules to be used in different dimensions.

Languages:

SPARSE_COUNT is available in a C++ version and a FORTRAN90 version and a MATLAB version.

Related Data and Programs:

MIXED, a library which creates a sparse grid dataset based on a mixed set of 1D factor rules.
