How do I factorize a matrix(m x n) into two factors (m x r, r x n) in Matlab? -

-

i want start mxn matrix , factorise 2 matrices mxr , rxn. r can greater dimensions of matrix a.

nnmf allows r< min(size(a))

is there way can factorise matrix 2 matrices?

there factorization functions available in matlab, see here: http://www.matrixlab-examples.com/matrix-decomposition.html

e.g. lu / qr - factorization, cholesky etc...

i need duration of audio file series of voice announcements need play app. have added audio files resources , play fine. sample code below works perfect intended purpose: return duration of audio files. here code: float getdurationofaudioresource(locationenum loc, context context){ float duration = 0; try { mediaplayer mp; mp = mediaplayer.create(context, getaudioresource(loc)); duration = mp.getduration(); mp.release(); mp = null; } catch (illegalstateexception e) {e.printstacktrace(); logerror(25, "testdescitem:fault::could not open mediaplayer object audio resource.");} return duration; } here's weird thing. code called in main activity prepares set of audio instructions given test. there no errors within activity. second activity called, long string of errors on logcat. 03-07 13:23:43.820: i/actionlogger(21435): gentest_info_test #0 created. 03-07 13:23:43.830: i/actionlogger(21435): gente
