Easy serialization of C++ Eigen matrices using HDF5.
The library is meant to be bare-bones (at least for now). It gets me 90% of what I want/need in a few hundred lines of code. It may also get you 90% (or even 100%) of what you need.
Because eigen3-hdf5 is a template library, there is nothing to link against (besides the HDF5 libraries).
Supports saving and restoring Eigen matrices and vectors of float, double, long double, int, unsigned int, and std::complex<>.
#include <eigen3-hdf5.hpp>
void save_matrix()
{
Eigen::Matrix3d mat;
mat << 1, 2, 3, 4, 5, 6, 7, 8, 9;
H5::H5File file("filename1.h5", H5F_ACC_TRUNC);
EigenHDF5::save(file, "MatrixDataSetName", mat);
}
void load_vector()
{
Eigen::Vector4i vec;
H5::H5File file("filename2.h5", H5F_ACC_RDONLY);
EigenHDF5::load(file, "VectorDataSetName", vec);
}
See the unittests directory for more examples.
I am using premake4 and googletest because I am familiar with them.
The unit tests currently write to specific files in the current directory. This could change, eventually.

eigen3-hdf5 using the regular C HDF5 API, not the C++ wrapper. Patches are welcome. :)RetroSearch is an open source project built by @garambo | Open a GitHub Issue
