neq.constraints.inplace

pmax.inplace

These functions modify objects (mainly matrix objects) in
 place, i.e. they act directly on the C pointer. Due to
 their side-effect, they are not meant to be called by the
 end-user.
<code>neq.constraints.inplace</code> apply unequality
 constraints in place.

internal

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.
