Welcome to Scilab 2026.0.0

Scilab 2026.0.0 is a new stable release of Scilab, the open-source platform for numerical computation.

Here is a tour of the changes since Scilab 2025.1.0.

Feature changes and additions

• New functions:
  • cdftnc(): Cumulative distribution function of the non-central student's T distribution.
  • dbscan(): Density-based clustering.
  • enumeration(): Get the enumeration of a classdef or an object.
  • estimate_bandwidth(): Estimate an appropriate bandwidth for mean shift clustering.
  • gallery(): Generate test matrices.
  • gradient(): Compute numerical gradient.
  • isa(): Check variable type.
  • meanshift(): Mean shift clustering algorithm.
  • methods(): Get accessible methods of a classdef or an object.
  • properties(): Get accessible properties of a classdef or an object.
  • sortrows(): Sort rows of a vector, matrix, table, or timeseries.
  • spset(): Set non-zero entries of a sparse matrix.
• Features improvements:
  • host() has been rewritten and is now used as a backend for all other functions that perform system calls (dos(), unix(), unix_g(), unix_s(), unix_w(), and unix_x()), which are now obsolete.
  • intersect() now manages duration, datetime, table, and timeseries types.
  • lib() can now load a library without exposing its symbols (default behavior remains unchanged).
  • setdiff() now manages duration, datetime, table, and timeseries types.
  • table(), and timeseries() now manage integers.
  • union() now manages duration, datetime, table, and timeseries types.
  • Options names are now case-insensitive for duration(), calendarDuration(), datetime(), timeseries(), table() functions.
• Language changes:
  • Classes/Objects can now be defined and used in Scilab based on the new classdef, enumeration, properties & methods keywords.
  • The end keyword can now be used to specify the last row/column index of an array, similarly to $.
• Graphics:
  • Axes handles can now have their own colormap. If not provided, then the parent figure colormap is used (as in previous versions).
• Xcos:
  • Diagrams are saved as SSP (System Structure and Parametrization) files by default. This setting can be edited in user preferences.
  • Users are now enabled to save their diagrams as COSF files.
  • COS format is no longer associated with Xcos under Windows.
  • SSP files are associated with Scilab during installation under Windows.

Detailed information about those improvements can be found in the CHANGES file.
