POWER_RULE, a C program which creates a power rule, that is, a multidimensional quadrature rule formed as a repeated product of a single one-dimensional quadrature rule.
Note that the three files that define the quadrature rule are assumed to have related names, of the form
For information on the form of these files, see the QUADRATURE_RULES directory listed below.

If the arguments are not supplied on the command line, the program will prompt for them.
The program will create these output files, which define the multidimensional quadrature rule:

POWER_RULE is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
CLENSHAW_CURTIS_RULE, a C program which defines a Clenshaw Curtis quadrature rule.
HERMITE_RULE, a C program which can compute and print a Gauss-Hermite quadrature rule.
LEGENDRE_RULE, a C program which computes a 1D Gauss-Legendre quadrature rule.
PRODUCT_RULE, a C program which constructs a product quadrature rule from distinct 1D factor rules.
QUADRATURE_RULES, a dataset directory which contains sets of files that define quadrature rules over various 1D intervals or multidimensional hypercubes.
QUADRULE, a C library which defines quadrature rules on a variety of intervals with different weight functions.
SANDIA_RULES, a C library which produces 1D quadrature rules of Chebyshev, Clenshaw Curtis, Fejer 2, Gegenbauer, generalized Hermite, generalized Laguerre, Hermite, Jacobi, Laguerre, Legendre and Patterson types.
TRUNCATED_NORMAL_RULE, a C program which computes a quadrature rule for a normal probability density function (PDF), also called a Gaussian distribution, that has been truncated to [A,+oo), (-oo,B] or [A,B].
