Welcome to Scilab 2025.0.0

Scilab 2025.0.0 is a new stable release of Scilab, the open-source platform for numerical computation.

Here is a tour of the changes since Scilab 2024.1.0.

Feature changes and additions

• New functions:
  • frank: Computes Frank matrix.
  • getdeprecated: Gets names of deprecated functions and replacement function names.
  • hilbm: Computes Hilbert matrix.
  • invhilb: Computes inverse of Hilbert matrix.
  • kmeans: K-means clustering function.
  • magic: Computes magic square matrix.
  • polyfit: Fits a curve with a polynomial.
  • polyval: Evaluates a polynomial for some given values.
  • vander: Computes Vandermonde matrix.
• Language changes:
  • Anonymous/Lambda functions are now available in Scilab using a dedicated syntax #(x) -> (x+1).
  • New simplified syntax to declare complex numbers: 1i and 1j (equivalent to 1*%i).
• Web Tools:
  • timeout optional parameter has been added to http_* functions.
  • http_upload can be used to upload a remote file with a different name as local one.
• Graphics:
  • New property "TooltipString" added for uimenu handles.
  • New properties "cdata_bounds" & "color_range" added for Fac3d handles.
  • "anti_aliasing" property value is now "8x" by default for graphic figures (Anti-aliasing was deactivated by default in previous versions).
  • "fractional_font" property value is now "on" by default for text handles (is was "off" by default in previous versions).
  • Graphics functions now return the handles they created: h = plot(), h = surf(), ... This feature can be used to replace h = gce() in some cases.
  • New way to manage rendering (raw text, LaTeX, MathML) of strings in graphics figures with:
    • "interpreter" property added for Text, Datatip, Label and Legend handles,
    • "tics_interpreters" property added for Axis handles,
    • "interpreters" property added for x_ticks, y_ticks and z_ticks for Axes handles.
• Other Improvements:
  • Some Scilab modules (`CACSD`, `Linear Algebra`, ...) have been updated to use the `arguments` block hence enhancing their performances.
  • pca() function now manages more input/output arguments.

In this version, extra effort has been expanded on fixing issues and stabilization. Detailed information about those improvements can be found in the CHANGES file.
