sparse_count

sparse_count, an Octave code 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, the code sparse_grid_mixed() allows different rules to be used in different dimensions.
