MATIO
An open-source C library for reading and writing binary MATLAB MAT files without requiring MATLAB.
What is MATIO?
Matio is an open-source C library for reading and writing binary MATLAB MAT files. It solves the problem of accessing MATLAB data formats in environments where MATLAB is not installed or where reliance on MATLAB's shared libraries is undesirable. The library supports multiple MAT file versions, including compressed and HDF5-based formats.
Developers and researchers working with scientific data who need to read or write MATLAB MAT files from C/C++ applications, especially in embedded systems, cross-platform tools, or open-source projects that cannot depend on MATLAB.
Matio provides a lightweight, standalone alternative to MATLAB's proprietary I/O libraries, offering full compatibility with MAT files without licensing restrictions. Its optional support for zlib and HDF5 ensures flexibility, while its cross-platform build systems simplify integration into diverse toolchains.
