 ## if you have a local armadillo installation, you will need to provide the directory during compile time and possible also link lblas and lapack 
 ## our recommendation is to use miniconda3 to do the installation
 ##	$ conda install -c conda-forge armadillo
 ## then you will have the appropriate lib and include files in your home directory under subdirectory miniconda3/
 ## so, replace USERNAME with your unix id on the following line and try this
