![]() Additional functions that appear after the first function are known as helper functions or local functions. Note that this is only true for the first function that appears in a. FreeMat installers are available for Windows and Mac OS X, and source and binary packages are available for Linux.įreeMat has features that are in progress and which are in the development version or are planned for the near future such as the widgets/GUI building and the FreeMat-to-MEX interface for porting MATLAB MEX files. So, for example, if the file is named foo.m, but the declaration uses bar for the name of the function, in FreeMat, it will still appear as function foo. Other UNIX environments (such as IRIX/SOLARIS). FreeMat currently supports Windows, Linux and Mac OS X are supported platforms. FreeMat supports decompositions of single and double types.įreeMat does not currently support GUI/Widgets. FreeMat has adopted a feature of IDL that is a modified form of keywords which allows users to call a function with the arguments to the function specified in an arbitrary order. In FreeMat, users can construct matrices with strings as contents, but users have to make sure that if the matrix has more than one row, that all the strings have the same length. FreeMat now also supports the so called dynamic-field indexing expressions where the fieldname is supplied through an expression instead of being explicitly provided. FreeMat now supports function handles, or function pointers where a function handle is an alias for a function or script that is stored in a variable. 3D volume rendering capability (via VTK)įreeMat is an environment for rapid engineering and scientific processing which is similar to commercial systems such as MATLAB from Mathworks and IDL from Research Systems, but is Open Source.įreeMat offers features such as a codeless interface to external C/C++/FORTRAN code, parallel/distributed algorithm development (via MPI), and advanced volume and 3D visualization capabilities.3D Plotting and visualization via OpenGL.Function pointers (eval and feval are fully supported).Native support for Mac OS X (no X11 server required).Codeless interface to external C/C++/FORTRAN code.Pass-by-reference support (an IDL feature).When you create Mat object from your pointer or from old C structs (CvMat, IplImage), Mat object will not free this memory. Full support for dynamic structure arrays cv::Mat will free memory only if it was allocated by create method (if Mat object owns this memory): Mat src(100, 100, CV32FC1) src.release() // will free memory. ![]() Heterogeneous array types (called "cell arrays" in MATLAB-speak) fully supported.Full control structure support (including, for, while, break, continue, etc.).Eigenvalue and singular value decompositions.Support for solving linear systems of equations via the divide operators.Built in arithmetic for manipulation of all supported data types.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.N-dimensional array manipulation (by default, N is limited to 6).
