I'm using Armadillo via RcppArmadillo and would like to save matrices in the HDF5 format. I manually reinstalled Armadillo in /home/me/armadillo-4.650.3, following option 1 as described here:
C++ building error for a simple code using armadillo and hdf5 libraries
However, even after reinstalling RcppArmadillo, it's still not possible save matrices in the HDF5 format. Can you help me make this possible?
