runtime,NMFList-method

Returns the CPU time required to compute all NMF fits in
 the list. It returns <code>NULL</code> if the list is empty. If
 no timing data are available, the sequential time is
 returned.

methods

Provides a framework to perform Non-negative Matrix
Factorization (NMF). The package implements a set of already published algorithms
and seeding methods, and provides a framework to test, develop and plug
new/custom algorithms. Most of the built-in algorithms have been optimized
in C++, and the main interface function provides an easy way of performing
parallel computations on multicore machines.
