This is a major release. It combines bug fixes, new features and
changes to existing features. Most notable among the new features are:
decomposition algorithms in the linear algebra package (LU, QR, Cholesky,
SVD, eigen decomposition) which are based on the popular JAMA API (but
much faster); support for sparse matrices and vectors;
support for any field-based matrix (Complex, Fraction ...);
support for genetic algorithms;
several new optimization algorithms (Dantzig's simplex for linear
constrained problems, conjugate gradient, Brent);
support for curve fitting with special cases for harmonic and polynomial
functions;
support for state derivative in ODE step handlers;
new multistep integrators (Adams-Bashforth and Adams-Moulton) with
variable stepsize;
regression algorithms;
rank transformations;
Mersenne twister pseudo random number generator.
This release is NOT source and binary compatible with earlier versions
of Commons Math. Starting with version 2.0 of the library, the minimal
version of the Java platform required to compile and use commons-math
is Java 5. Users are encouraged to upgrade to this version, as in addition
to new features, this release includes numerous bug fixes. Users of
Commons Math 1.0-1.2 should recompile their code against the 2.0 jar.
Most of the compilation errors users will encounter after the switch
will be due to classes moved due to package reorganization. These errors
are simply solved by adjusting the import statements in users code.">
