SPARSE_GRID_COMPOSITE
Sparse Grids Based on 1D Composite Rules


SPARSE_GRID_COMPOSITE is a MATLAB library which can be used to compute the points and weights of a Smolyak sparse grid, based on a 1-dimensional composite quadrature rule.

Currently, the library only allows composite rules of the 1 point midpoint formula. A 1D composite rule of the midpoint rule is suitable for integration of functions with low or variable smoothness. A sparse grid formed from such rules can better handle multidimensional integrands with limited smoothness.

Of course, for both the 1D composite rule and the sparse grid rule, the repeated use of the midpoint rule limits the order of accuracy of the quadrature; therefore, if the integrand is known to be of higher smoothness, other approaches will produce an accurate answer more quickly.
