Detailed Description

Class for the "Hungarian" pairing algorithm. Adapted for Vincia from an implementation by M. Buehren and C. Ma, see notices below. This is a C++ wrapper with slight modification of a hungarian algorithm implementation by Markus Buehren. The original implementation is a few mex-functions for use in MATLAB, found here: http:///www.mathworks.com/matlabcentral/fileexchange/ 6543-functions-for-the-rectangular-assignment-problem

double solve ( std::vector< std::vector< double > > &  distMatrix,
std::vector< int > &  assignment 
)

Function wrapper for solving assignment problem.

Class for the "Hungarian" pairing algorithm.

A single function wrapper for solving assignment problem.

Fill in the distMatrixIn. Mind the index is "i + nRows * j". Here the cost matrix of size MxN is defined as a double precision array of N*M elements. In the solving functions matrices are seen to be saved MATLAB-internally in row-order. (i.e. the matrix [1 2; 3 4] will be stored as a vector [1 3 2 4], NOT [1 2 3 4]).

Call solving function.
