Complex Matrix Factorization

nmfStandard.m

Standard NMF Interations to minimize Eucledian distance with parameters as

• nIter -> Number of Iterations
• fixedX -> to keep X fixed while interating
• X -> to initialize X with given values

nmfWithPhase4.m

Mis-named as nmfWithPhase, it is basically performing complex matrix factorization based on the paper http://arxiv-web3.library.cornell.edu/pdf/1411.6741v1.pdf It has a single dependency on nmfStandard.m which it uses to perform Complex Matrix Factorization

• Outputs
  • X -> Complex Factorized Vector Sets (PxQ)
  • H -> Real Factorized Weights (QxR)
  • Xc -> Real Matrix which can be appropriatly transformed to get X (2Px2Q)
