Non-negative matrix factorization
Tue, 08/06/2019 - 09:01 am
I am using the principal component analysis function implemented in Igor -- it works well but I end up with negative contributions which I want to avoid.
Is there a function in Igor to do non-negative matrix factorization? That would work well with the data I have.
I typically work with 2D waves, with each column being a dataset (pair distribution function data).
