A more friendly interface of the Cuba integration library. An example is in test.c. After you have read the manual of Cuba, the usage is pretty straightforward as shown in test.c.
The code amount is fairly small, thus, to use this interface is to copy the source files into your project. To download the source files, you can either use git:
git clone https://github.com/xuhdev/frcuba.git
Or follow this link to download the tarball:
curl -L https://github.com/xuhdev/frcuba/archive/master.tar.gz >frcuba.tar.gz
