How to find coordinates of point in 3D given coordinates of few(more than 3 non linear/noncoplaner) points and distance from desired point using MATLAB?

suppose given five points are: [2.6643 1.4664 0.3019] [7.1360 1.4661 1.7333] [5.3205 -3.1543 0.5792] [3.1621 -1.1489 -2.4490] [8.0418 -0.6020 -0.1050]

and their respective distances from point(x,y,z) are: 0.0376, 0.0418, 0.1882, 0.0753, 0.0538

How can i find x, y and z using MATLAB?

  • I answered a similar question here. The answer is easily extended to 3-D. Once you have the matrices set up, use the "" operator to solve the system. – AnonSubmitter85 Jan 15 '14 at 13:32

Write the sum of the square distances as a function, then use one of its minimization routines.
