Detailed Description

This operator computes the log barrier term for the doubly bounded inequalities:
 xl <= x < xu
The barrier is computed as:
 sum{ log( x(i) - xl(i) ) + log( xu(i) - x(i) ) , for i = 1...n }
To call this operator you must pass in the vectors in the order: v0 = x, v1 = xl, v2 = xu.

The operation performed is:

 element-wise reduction : log_result += log(v0(i) - v1(i)) + log(v2(i) - v0(i)), i = 1...n

This operator class implementation was created automatically by 'new_rtop.pl'.

ToDo: Write the documentation for this class!
