Problems:
- monte carlo (computing PI)
- integral (computing integral using trapezoid method)
- matrics multiplication
Sequential and parallel (using MPI) programs.
$ cd c-libs
$ make libs$ cd integral
$ make$ cd monte_carlo
$ make$ cd matrix_multiplication
$ makeProgram will not check if input data is correct!
f(x) = e^(-x^2) -- you can provide another f(x) in lib.c
