Standard library for Matlab

Matlab or GNU Octave users coming from other languages will benefit from the functionality contained within this user-developed, unofficial "stdlib" standard library of functions. These system, filesystem, and HDF5 / HDF4 / NetCDF functions are used across numerous projects.

Matlab R2020b is the minimum required due to use of arguments and mustBeTextScalar syntax. URLs (e.g. https://, s3:// and similar) are treated as not existing.

Self-tests

The self-tests require at least Matlab R2020b and can be run from the matlab-stdlib/ directory.

Matlab R2024b and newer:

buildtool test

Matlab R2023a..R2024a, inclusive:

buildtool test_nomex
buildtool test_java
buildtool test_exe
buildtool test_mex

Matlab R2022b:

buildtool test_nomex
buildtool test_java

Matlab older than R2022b:

run('test/test_nomex.m')

MEX functions

With Matlab R2023a and newer, optionally build high-performance MEX functions (the same functions are provided by default without MEX) from the Matlab prompt in Matlab R2023a or newer:

buildtool mex

If just building MEX functions for the first time, to ensure the MEX functions are used instead of the plain Matlab script, one-time type clear functions in Matlab.

Java-based functions

Most Matlab-stdlib filesystem functions work without the Java interface. If Matlab was started without Java using -nojvm, most Matlab-stdlib functions still work. This CI job tests without Java.
