Releasev0.4.9 (early, 0.x) · Apache-2.0 (code), CC BY-SA 4.0 (docs)
LinksGitHub · Documentation · Download
My roleAuthor
  • One engine, one syntax from measurement to figure: publication-quality plots as SVG, PDF and TikZ
  • More than 1,300 documented functions: filters, FFT, spectrograms, wavelets, dense & sparse linear algebra, ODE solvers, statistics, classic ML, impedance-spectroscopy tools
  • Reads and writes Excel, Word, PowerPoint, PDF, NumPy and HDF5 files
  • Fails loudly: an unread keyword, a shape mismatch or a singular matrix is an error, never a guess
  • Command-line tool with REPL, test and format commands, Qu Studio IDE, Jupyter kernel, editor plugins · Windows, Linux & macOS (Apple silicon)

Windows builds are not yet code-signed; verify the SHA-256 on the release page.
