Matrices multiplication example
Universal script for gnuplot (env vars specify data and output)
Makefile for demo. For this moment it only creates matrices multiplication demo. It soon will be extended by pi calculation.
Demo script that runs matrix multiplication program for thread numbers from 1 to specified number. Additionally it runs the program without specifying threads number (then number of threads equals to cores number). It generates data file with execution times and plots (with gnuplot) times' graph.
