WebUser Class for performing numerical integration of a function in one dimension. It uses the plug-in manager to load advanced numerical integration algorithms from GSL, which reimplements the algorithms used in the QUADPACK, a numerical integration package written in Fortran. Various types of adaptive and non-adaptive integration are supported. WebStatistical test whether two one-dimensional sets of points are compatible with coming from the same parent distribution, using the Kolmogorov test. That is, it is used to compare two experimental distributions of unbinned data. Input: a,b: One-dimensional arrays of length na, nb, respectively.
