Hi, Im trying to use your code for point cloud of small point (about 10 -20 points per pointscloud ) in order to test that i use a .xyz containing 20 points of the the 20 vertices of a dodecahedron (fixed point cloud). i created a second files of this one where i moved each X coordinate by ading +10 (movable point cloud) .
Im feeding the algorithm with this two files and the algorithm give me back this matrix :
H =
[ 0.930487 0.366326 0.000000 -9.831626]
[ -0.366326 0.930487 0.000000 0.130998]
[ -0.000000 -0.000000 1.000000 0.000000]
[ 0.000000 0.000000 0.000000 1.000000]
i saw on the README file that to move a point to the position of the fixed, i have to do this operation to get the movable point tof fit the fixed point ;
Xt = H*X
im doing so :
X =[ 10.57735027; 0.57735027 ;0.57735027 ; 1] coordinate of first point in the movable point cloud
H =
[ 0.930487 0.366326 0.000000 -9.831626]
[ -0.366326 0.930487 0.000000 0.130998]
[ -0.000000 -0.000000 1.000000 0.000000]
[ 0.000000 0.000000 0.000000 1.000000]
but when i'm trying it, im not recovering the correct point :
Xt=X*A
Xt=[0.2220
-3.2065
0.5774
1.0000]
and if i understand well i should get the coordinate of this :
xt =0.57735027 0.57735027 0.57735027 1 wich is the coordinate of the first point in the fixed point cloud
so im asking myself if the algorithm is working properly . or im not using it correctly

here is the image of the result of the multiplication of the matrix (i did on Matlab online )
and here the algorithm :
if you have any clue about it would help me !
