Function distance #
Calculates: The eucledian distance between two points in N-dimensional spaces. Distance between point and a line in 2 and 3 dimensional spaces. Pairwise distance between a set of 2D or 3D points NOTE: When substituting coefficients of a line(a, b and c), use ax + by + c = 0 instead of ax + by = c For parametric equation of a 3D line, x0, y0, z0, a, b, c are from: (x−x0, y−y0, z−z0) = t(a, b, c)
