MATLAB to PHClab

PHClab is a collection of scripts which call PHCpack from within a MATLAB or Octave session. PHCpack is a software package for Polynomial Homotopy Continuation, to numerically solve systems of polynomial equations.
However, PHClab does not allow divisions and parenthesis in its syntax. They can be removed by evaluating the expression using variable precision arithmetic and with some string manipulations.
