Intersection point of lines in 3D space

Finding intersection point of lines in 3D space (two or more lines).

Description

Finding intersection point of lines in 3D space (two or more lines).
Will return point with the minimum sum of squared distances from point to lines (LSM-method, using pseudoinverse).

% PA : Nx3-matrix containing starting point of N lines
% PB : Nx3-matrix containing end point of N lines
% P_Intersect : Best intersection point of the N lines, in least squares sense.
% distances : Distances from intersection point to the input lines

Works great. Thanks for adding it up.
