runtime.all,NMFfitXn-method

If no time data is available from in slot
 &#8216;runtime.all&#8217; and argument <code>null=TRUE</code>, then
 the sequential time as computed by <code>seqtime</code>
 is returned, and a warning is thrown unless
 <code>warning=FALSE</code>.

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.

runtime.all,NMFfitXn-method function

<dl> <dt>null</dt>
<dd>a logical that indicates if the sequential
 time should be returned if no time data is available in
 slot &#8216;runtime.all&#8217;.</dd>
 <dt>warning</dt>
<dd>a logical that indicates if a warning
 should be thrown if the sequential time is returned
 instead of the real CPU time.</dd>
 <dt>object</dt>
<dd>an object computed using some algorithm, or
 that describes an algorithm itself.</dd></dl>
