Release Notes

New features in this release include:
  • 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.

This release also fixes a bug in our SVD algorithm which occured for some matrices with zero singular values, a bug in the Sample class's inverse CDF (i.e. percentile to score) method, and several other bugs.

Reviews for this release

Was looking for a long time a C# fitting library with such clear API. Really brilliant.
