def	__init__ (self, params)
def	computeBilinearForm (self, grid)
def	computeBilinearFormEntry (self, basis, gpi, gpj)
def	getKey (self, gps)

Detailed Description

Generate the a quadrature strategy that appriximates the probability
density in each dimension with a piecewise constant function. Each constant
function is determined by the density evaluated at the center of the support
of the corresponding basis function.
