Methods for multivariate Quadrature (numerical integration)
plots an NIGrid-object
prints characteristic information for an NIGrid-object
computes the approximated Integral
reads a quadrature-rule from a text file
moves, rescales and/or rotates a multidimensional grid.
returns the size of an NIGrid-object
Provides methods to construct multivariate grids, which can be used for multivariate quadrature. This grids can be based on different quadrature rules like Newton-Cotes formulas (trapezoidal-, Simpson's- rule, ...) or Gauss quadrature (Gauss-Hermite, Gauss-Legendre, ...). For the construction of the multidimensional grid the product-rule or the combination- technique can be applied.
