What's new in Meta Numerics 2.2.0
Aug 12, 2013
- Multidimensional integration.
- Polynomial interpolation, arithmetic, and calculus.
- Faster non-uniform deviates and probit functions.
- Exact Kendall, Kolmogorov-Smirnov, Kuiper, and Spearmann null distributions for small sample sizes.
- Fit samples to Gamma and Lognormal distributions. Improved performance of other FitToSample methods.
- Matrix powers and utility methods.
New in Meta Numerics 2.1.0 (Aug 12, 2013)
- Improved FFT. Fourier transforms are fast for all lengths, even those with large prime factors.
- More advanced functions: incomplete elliptic integrals of the second kind, the polygamma function, and complex exponential integrals. New Bessel function methods simultaneously return (J, J', Y, Y') or (I, I', K, K'). New advanced integer functions include primality testing and harmonic numbers.
- SpareSquareMatrix now supports the iterative solution of large systems of equations.
- New statistical analysis features include sample transformations, polynomial regression for bivariate samples, and fitting samples to beta distributions.
