POLYNOMIALCURVECURVATURE Compute the local curvature of a polynomial curve.

   KAPPA = polynomialCurveCurvature(T, XCOEF, YCOEF)
   XCOEF and YCOEF are row vectors of coefficients, in the form:
       [a0 a1 a2 ... an]
   KAPPA is the local curvature of the polynomial curve, computed for
   position T. If T is a vector, KAPPA has the same length as T.

   KAPPA = polynomialCurveCurvature(T, COEFS)
   COEFS is either a 2xN matrix (one row for the coefficients of each
   coordinate), or a cell array.

   Example
   polynomialCurveCurvature
