ylag Function

public function ylag(xi, x, y, ind1, n1, imax)

Lagrangian interpolation xi is interpolated entry into x-array n is the order of lagrangran interpolation y is array from which ylag is obtained by interpolation ind is the min-i for x(i).gt.xi if ind=0,x-array will be searched imax is max index of x-and y-arrays
