A simple set of codes to simulate (semi-numerically) HI maps during reionization.
Use the makefile for compilation in the following manner:
make ionz_main
It will create the executable 'ionz_main'
You need to install FFTW 2.x.x with following flags: '--enable-float' and '--enable-type-prefix' to compile this set of codes.
