GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.

Merged Allow functions for Field.coordinate_transform

seitz/pystencils:functional_coordinate_transform into master

Merged Stephan Seitz requested to merge seitz/pystencils:functional_coordinate_transform into master 5 years ago

    field.coordinate_transform = lambda x: sympy.Matrix((x.norm(), sympy.atan2(*x) / (2 * sympy.pi) * field.shape[1]))
