the class AbstractIntIntMap method keys.

Example 7 with IntArrayList

use of cern.colt.list.IntArrayList in project tdq-studio-se by Talend.

the class DoubleMatrix1D method viewSelection.

/**
 *Constructs and returns a new <i>selection view</i> that is a matrix holding the cells matching the given condition.
 *Applies the condition to each cell and takes only those cells where <tt>condition.apply(get(i))</tt> yields <tt>true</tt>.

 *matrix = 0 1 2 3

 *-->
 *matrix ==  0 2

 *For further examples, see the <a href="package-summary.html#FunctionObjects">package doc</a>.
 *The returned view is backed by this matrix, so changes in the returned view are reflected in this matrix, and vice-versa.
