Examples of walkInOptimizedOrder()

org.apache.commons.math.linear.Array2DRowRealMatrix.walkInOptimizedOrder()
org.apache.commons.math.linear.RealMatrix.walkInOptimizedOrder()
Visit (and possibly change) all matrix entries using the fastest possible order.
The fastest walking order depends on the exact matrix class. It may be different from traditional row or column orders.
@param visitor visitor used to process all matrix entries @exception MatrixVisitorException if the visitor cannot process an entry @see #walkInRowOrder(RealMatrixChangingVisitor) @see #walkInRowOrder(RealMatrixPreservingVisitor) @see #walkInRowOrder(RealMatrixChangingVisitor,int,int,int,int) @see #walkInRowOrder(RealMatrixPreservingVisitor,int,int,int,int) @see #walkInColumnOrder(RealMatrixChangingVisitor) @see #walkInColumnOrder(RealMatrixPreservingVisitor) @see #walkInColumnOrder(RealMatrixChangingVisitor,int,int,int,int) @see #walkInColumnOrder(RealMatrixPreservingVisitor,int,int,int,int) @see #walkInOptimizedOrder(RealMatrixPreservingVisitor) @see #walkInOptimizedOrder(RealMatrixChangingVisitor,int,int,int,int) @see #walkInOptimizedOrder(RealMatrixPreservingVisitor,int,int,int,int) @return the value returned by {@link RealMatrixChangingVisitor#end()} at the endof the walk
org.apache.commons.math3.linear.Array2DRowRealMatrix.walkInOptimizedOrder()
Visits (but does not alter) all entries of this vector in optimized order. The order in which the entries are visited is selected so as to lead to the most efficient implementation; it might depend on the concrete implementation of this abstract class. @param visitor the visitor to be used to process the entries of thisvector @return the value returned by {@link FieldVectorPreservingVisitor#end()}at the end of the walk @since 3.3
