abstract: "<p>To our knowledge no Python package is available for conversion between cartesian and polar coordinates, so we made one for convenience.</p><p>The package converts numpy arrays where the last dimension contains x, y or magnitude, orientation coordinates.</p><p>When working with cupy arrays, the package performs calculations on the GPU automatically.</p>"
