It is written in C but part of the codes were originally in fortan. Unscaled and scaled modified Bessel functions of first and second kind of real order and complex argument. Dawson's integral, Fresnel integrals, dilogarithm, Riemann zeta function and Riemann zeta function of two arguments. Exponential integral Ei, sine and cosine integrals and hyperbolic sine and cosine integrals. A wide list of links and resources for Mathcad can be found here .
Psi function can now deal with complex arguments.
Legendre polynomials and associated functions with their normalised versions and spherical harmonics are now available. Example files are now provided, which show some application of the functions for electromagnetic problems. Logarithmic gamma function, beta function and logarithmic beta function can deal with complex arguments. Legendre's canonical incomplete, complete and associated elliptic integral of the third kind and Carlson's incomplete elliptic integral of the first, second and third kind are now available. The Mathcad file mathlib.mcd provided with the libray contains usage examples for the functions.
