Looks ok to me ``` def reflection_coefficient(z, z0): return np.abs((z - z0) / (z + z0)) ```

This is still a bug with Ubuntu 20.04. Having to hack the config.ac. Has anyone convert this project to using cmake?

on ubuntu 20.04 clapack.h is located at /usr/include/x86_64-linux-gnu libs at /usr/lib/x86_64-linux-gnu
