intprb_getvariance — Compute the variance.
v = intprb_getvariance ( n , p , nprob )
a floating point integer, the dimension of the space
a floating point matrix, the parameters of the problem
the problem number
a 1 x 1 matrix of doubles, the variance
It is an interface function which calls the function getfunc (which selects appropriate test fuction based on nprob). If the variance is known, the returned value of v is unity. If the variance is unknown, the returned value of v is the empty matrix. For Genz's functions, the variance is unknown.
See the "Integration Problems User's Manual" available in the doc directory of this toolbox for a detailed description of this function.
