## qutil.matlab

In this module there are functions that are helpful for reading `.mat` files, especially those created with special measure. If you simply want to open a random `.mat` file you can use `hdf5storage.loadmat`.

## qutil.linalg

This module provides several handy linear algebra functions. While some are implemented elsewhere, the implementation here is typically speedier for large arrays. For example, `pauli_expm` exploits the fact that a matrix exponential of Pauli matrices can be written as a cosine times the identity matrix plus a sine times the Paulis to speed up the calculation.

For an overview of the included functions, see the module docstring.

## qutil.qi

In this module there are some quantities and functions related to quantum information, like the Pauli matrices in different data types.
