assignment vector and trying to reproduce the cut castle example

[tractatus]

Hi,

Thanks for making the source available code to this highly valuable technique you made.

Im trying to use SPOT to arrive at an injective mapping between two point clouds of different sizes (asymmetric assignment problem).

So Im not necessarily interested in the transformation obtained by FIST but rather the mapping.

Nevertheless, I tried to reproduce the castle example using mainFIST.cpp by rotating and shrinking the cut castle (150k) and running it against the complete castle (200k) but the transformation doesnt seem to make sense and when I also print the output from the assignment vector corr1d it doesnt seem to make sense (especially if I scramble the row order in the array of the point clouds, it will always just give a more or less ascending index).

Helpful for any pointers on how to resolve this. I might be missing some info.
