Triangulation: Calculate the 4th point(s) of a tetreder

3 points in space and their distance to common points are given, which position is calculated.

Description

3 points in space and their distance to common points are given, which position is calculated.
Calculation is based upon an linear algebra method.

Example:
p1=[0,0,0]; p2=[1,0,0]; p3=[1,1,0]
[p4a,p4b]=triangu3D(p1,p2,p3,10,10.2,10.4);
disp([p4a;p4b]);

Function can be used for triangulation problems or GPS-simulation.
