Hi, The demos for both of the new nmf_pg and nmf_bpas functions fail for me.
In case of nmf_pg, the demo uses the text_waitbar function from the miscellaneous package, but that package is not a linear-algebra dependency. The demo works if I load the miscellaneous package manually. In the last line of the nmf_bpas demo, norm(H_org) causes a Fortran error. Computing the 2-norm of a fat matrix probably uses svd. But H_org has size [10,200], and svd of a fat matrix is broken in lapack 3.4.0. It is fixed in lapack 3.4.1. So this report is just for your information. Please find the output of either demo below.
