angle_xy

PlasmaCalcs.quantities.patterns.vector_arithmetic.angle_xy(A)

return angle between +xhat and A, in the xy plane, in radians.

A should be a DataArray (or Dataset) with x and y in ‘component’ dimension.

A can be any vector (does not need to be a unit vector, but it can be.)

[Implementation currently just returns xarray_angle_xy(A)]
