v0.9.9

Added

• Add an automated test suite for validation of the software. Tests are executed automatically on Travis CI whenever changes are pushed to GitHub. Install with new option [test] (or [dev]) and use pytest to run the tests locally.

Changed

• Check that D is well behaved at the expected extrema of the solution when invoking solve(). If solve() determines that the problem cannot be solved, the function will now raise a ValueError immediately without performing any iterations.
• Improve error message when attempting to use the 'explicit' method of solve() and solve_flowrate() with SciPy older than 1.4.0.
• Improve reference documentation.

Fixed

• Fix examples/1INFILTR case with NumPy versions lower than 1.16.
• Fix examples/HF135/inverse2.py failure in some environments.
• Fix problem statement in 'Usage' section of README file.
