FreeMat v4.0 User Manual

About this manual

This manual covers everything needed to get started with FreeMat version 4.0, including installation on Linux, Windows and macOS, variable and array definitions, built‑in functions, mathematical operators, flow‑control statements, and a full reference of the FreeMat function library. Each topic is presented with usage syntax and examples.

Later chapters describe the external interface, showing how to import foreign C functions, load shared libraries, and use the import and loadlib commands to extend FreeMat with custom code.

Frequently asked questions

How do I install FreeMat on Windows?

See section 1.1.3 which provides Windows installation instructions.

How can I call a function from a shared C library in FreeMat?

Use the import function, which lets you call compiled C functions as if they were FreeMat functions.

What command loads a library function directly without using import?

Use the loadlib function, which adds a library function to FreeMat dynamically.
