Non-negative matrix factorization code

[buupq]

Hello,

I'm looking for the non-negative matrix factorization (NNMF) source code. I checked several linear algebra libraries (e.g., LaPack, mkl), but it seems that this subroutine is not available. Does anyone know where I can find this source code?

https://en.wikipedia.org/wiki/Non-negative_matrix_factorization#cite_note-23

Thank you!
