| org.hipparchus.analysis.function | 
 
      The  
function package contains function objects that wrap the
      methods contained in Math, as well as common
      mathematical functions such as the gaussian and sinc functions. | 
| org.hipparchus.analysis.polynomials | 
 Univariate real polynomials implementations, seen as differentiable
     univariate real functions. 
 | 
| org.hipparchus.fitting | 
 Classes to perform curve fitting.
