CyRK v0.5.0

Changes

New Features

• cyrk_ode now supports both float and complex-typed y and dydt functions.
  • Resolves issue 3. (Fix made by David Meyer)

Performance

• Converted various ints to shorts, chars, or Py_ssize_t. Py_ssize_t is recommended by Cython for loop integers to better support 64-bit architecture.
• Added custom interpolation functions which, depending on the size of the array, can be up to 10x faster than numpys.
• Removed unnecessarily variables from cyrk_ode.
• Had to turn off fastmath for nbrk_ode. See issue 24. This negatively impacted the numba integrator's performance by around 5%.

Other Changes:

• Refactored, cleaned up, and added comments and docstrings to cyrk_ode.
• Changed both nbrk_ode and cyrk_ode tests to use pytest parameterization.
• Changed the accuracy test for both nbrk_ode and cyrk_ode to check against a known function.
• Added openmp dependence during compile time to allow for the use of prange.
• Moved cyrk_ode's Runge-Kutta constants to a separate module CyRK.rk.

Bug Fixes:

• Fixed issue (for nbrk_ode and cyrk_ode) where incorrect step size could be used due to bad minimum step check (see issue 20).
