Description
            This toolbox consists of open-source solvers for a variety of optimization
problems: CLP for linear optimization, CBC for integer linear optimization,
IPOPT (with MUMPS) for nonlinear optimization, and BONMIN for integer nonlinear
optimization. 

On latest Ubuntu releases such as Ubuntu 19.10, libgfortran4 has to be
installed. This can be done by executing the command apt-get install
libgfortran4.

Features
---------
* fot_linprog: Solves a linear optimization problem.
 	
* fot_intlinprog: Solves a mixed-integer linear optimization problem in
intlinprog format with CBC.
  
* fot_quadprog: Solves a quadratic optimization problem.
  
* fot_quadprogmat: Solves a quadratic optimization problem (with input in
Matlab
  format).
