library to solve the system of linear equations

[Yura]

Dear All, Thank you so much for your replies and hints! I got it 
working today. All the libraries are properly linked and the 
Equation solver runs smoothly.

The compilers turned out to be problematic though. The "Mir" 
library does not work with the Ubuntu 18.04 gdc and ldc 
compilers. I have managed to install the latest version dmd, and 
it works. But I suspect that the dmd compiler is not optimal in 
terms of performance. The question becomes whether it is possible 
to install the most recent ldc and gdc compilers on Ubuntu 18.04?

The good thing is that I have also managed to get this code 
working in parallel.

Thank you again!
