class ROOT::Math::FastInverter< idim, n >

Fast Matrix Inverter class Class to specialize calls to Dinv.

Dinv computes the inverse of a square matrix if dimension idim and order n. The content of the matrix will be replaced by its inverse. In case the inversion fails, the matrix content is destroyed. Invert specializes Dinv by the matrix order. E.g. if the order of the matrix is less than 5 , the class implements Cramers rule. Be careful that for matrix with high condition the accuracy of the Cramer rule is much poorer
