Calculates the largest multiple of a vector that can be added to this vector while keeping each element of this vector nonnegative.

Synopsis

#include "tao_solver.h"  
int TaoVec::StepMax(TaoVec* vv,double *step1)

Input Parameters

vv -the step direction

Input Parameters

step1 -the maximum stepsize

Note

This vector should contain all positive elements.

Note

If there is no maximum steplength, the output scalar may be set to TAO_INFINITY.
