    Release Notes: Bugfixes. Extension of the (in)complete and regularized Gamma functions and the complete log-Gamma, Digamma, Beta, and log-Beta functions to the complex plane. Extension of the general partial harmonic function to the complex plane. This can be used to approximate the Riemann zeta function for complex arguments to about 6 digits precision. Extension of the Pochhammer symbol (raising factorial) to the complex plane.

      Release Notes: Bugs were fixed. Descriptions were added for the implementation of some 50 constants (now: 98), the statistical means, some statistical distributions, some special functions, and basic matrix operations rounding. Some entries were added to the glossary. More illustrations were added. About 100 more literature references were added.

            Release Notes: Minor bugfixes, the addition of a Vector data type for complex vectors, vector operations (+, -, /, *, dot, and cross), FFT for complex 1-d data, combinatorical functions, and Roman-Arabic number conversion.

              Release Notes: Bugs were fixed, especially for the complex numbers. Matrix decompositions (QR, LUP, Eigen, SVD) were added. Some helper functions for matrix handling were added.

                Release Notes: Bugfixes. A Matrix class has been added for complex matrices, as well as the matrix operators +, -, *, /, =, det, adj, trace, trans, conj. trans, rot90, size, inv,abs, 1-norm, inf-norm, 2-norm, some helpers, some constant matrices, and some more complex number operators (rounding and comparing).

                  Release Notes: Several small but annoying bugs have been fixed. A complex data type has been added with all basic operations (+, -, /, *, %, fmod, pow, log, and exp, to name just a few) including a set of trigonometric functions with their inverse, hyperbole, and inverse hyperbole counterparts together with a couple of helpers. A linear, square, and cubic solver have been added, and thus eigenvalues for 2x2 and 3x3 real matrices.
