Generate the sparse multidimensional Gaussian quadrature grids
GQdk(d = 1L, k = 1L)
d |
integer scalar - the dimension of the function
to be integrated with respect to the standard
|
k |
integer scalar - the order of the grid. A grid
of order |
a matrix with d + 1 columns. The first column is
the weights and the remaining d columns are the
node coordinates.
The number of nodes gets very large very quickly with
increasing d and k. See the charts at
