The top level README.TXT includes instructions on how to build FreeMat on all three platforms (Linux, Mac OS X, and Mingw32).ĭocumentation has been migrated to doxygen.Ī number of improvements have been made to the JIT back end. Global variables are shared by all templates, even if they belong to different name spaces because of import-ing. Release of FreeMat 4.2 -This version includes a number of bug fixes and some cleaned up tests and documentation.įreeMat is now easier to build. Native support for Mac OS X (no X11 server required).įunction pointers (eval and feval are fully supported).ģD Plotting and visualization via OpenGL.ģD volume rendering capability (via VTK). Check for variable type changes between running JIT compiled code. Pass-by-reference support (an IDL feature).Ĭodeless interface to external C/C++/FORTRAN code. FreeMAT Vector/Matrix variables can be called by (single-) pointer variables. Here's the current approach that FreeMat takes is: Compile code that would most benefit from speedup (loops, functions) If code cannot be compiled fall back to using the interpreter (slow, but at least you always get an answer). Note that sometimes a variable can work as more than one type An ordinal variable can also be used as a quantitative variable if the scale is numeric and doesn’t need to be kept as discrete integers. Heterogeneous array types (called "cell arrays" in MATLAB-speak) fully supported.įull support for dynamic structure arrays. You can create new variables in the workspace by running MATLAB code or using existing variables. There are three types of categorical variables: binary, nominal, and ordinal variables. Support for solving linear systems of equations via the divide operators.Įigenvalue and singular value decompositions.įull control structure support (including, for, while, break, continue, etc.). Support for 8,16, and 32 bit integer types (signed and unsigned), 32 and 64 bit floating point types, and 64 and 128 bit complex types.īuilt in arithmetic for manipulation of all supported data types. ![]() ![]() N-dimensional array manipulation (by default, N is limited to 6). When you run the program it comes up in a window and prints a prompt >. FreeMat is available under the GPL license. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source. To create a script, simply type the commands, functions, numbers and variables into the editor window as if you were typing into the Command Window. FreeMat is a free environment for rapid engineering and scientific prototyping and data processing.
