TinyMAT

A (partly templated) C++ library to handle writing simple Matlab(r) MAT file in Version "MATLAB 5.0" or higher

This library implements a very simple interface to write Matlab MAT file (level 5), as described in http://www.mathworks.de/help/pdf_doc/matlab/matfile_format.pdf

It is licensed under the terms of the GNU Lesser general Public license (LGPL) >=2.1

Example

The following example code writes some arrays and matrices into a MAT-file:

TinyMATWriterFile* mat=TinyMATWriter_open("test.mat");
if (mat) {
	// a 3D matrix in row-major
	double mat432[4*3*2]= {
	    1,2,3,
		4,5,6,

		10,20,30,
		40,50,60,

		100,200,300,
		400,500,600,

		1000,2000,3000,
		4000,5000,6000,
	};
	int32_t mat432_size[3] = {3,2,4}; // columns, rows, matrices,...

	// a struct as a map of doubles
	std::map<std::string, double> mp1;
	mp1["x"]=100;
	mp1["y"]=200;
	mp1["z"]=300;
	mp1["longname"]=10000*M_PI;

	TinyMATWriter_writeStruct(mat, "struct1", mp1);
	TinyMATWriter_writeMatrixND_rowmajor(mat, "matrix432", mat432, mat432_size, 3);

	TinyMATWriter_close(mat);
}

Library Bindings

• There exists a plugin for the CImg image processing library, that uses TinyMATWriter: https://github.com/dtschump/CImg/blob/master/plugins/tinymatwriter.h .
