}

Install

pip install matrixor

or, after a git clone:

python3 setup.py install

Run

Align two models with Absolute Orientation + Scaling and return RMSE

To align two embeddings, run:

matrixor align \
  --matrix-1 /abs/path/to/xxx.vec.npy  \
  --matrix-2 /abs/path/to/yyy.vec.npy \

pass in the --average to return the averaged RMSE by aligning A and B then B and A (alignment may not be symmetric due to floating point average)
