Release Notes

There is a ton of new and improved functionality in this major release:
  • Singular Value Decomposition (SVD), sparse matrices, matrix norms, and a new matrix hierarchy
  • Fast Fourier Transforms (FFT), including non-power-of-2 lengths
  • Principal Component Analysis (PCA), logistic regression, Kruskal-Wallis test
  • Easier to load data from databases or Excel spreadsheets
  • More distributions: Gamma, Pearson, discrete uniform, discrete geometric
  • Faster, dedicated methods to fit distributions to samples and generate nonuniform random deviates

Because this is a major release, we took the oportunity to improve our API in ways that may not be backwards-compatible (see our Versioning policy). We did not, however, remove any functionality. Any previous code does not compile against this new version should be easy to adapt; if you have any difficulties you can't immediately figure out, just ask in our Discussion Forum.
