Linked matrix factorization (LMF) code for the integration of multiple linked data matrices [1], written primarily by Michael O'Connell.

'lmf_perm' performs a joint and individual LMF decomposiion with ranks selected by perumtation testing.

'lmf.cv' performs a joint and individual LMF decomposition with ranks selected by cross-validation.

'lmf_impute' performs missing value imputation using joing LMF

'lmf_impute_ji' performs missing value imputation using a joint and invidual LMG (LMF-JIVE)
