plasmapy.analysis.nullpoint

Functionality to find and analyze 3D magnetic null points.

Attention

This functionality is under development. Backward incompatible changes might occur in future releases.

Classes

NullPoint(null_loc, classification)	A class for defining a null point in 3D space.
Point(loc)	Abstract class for defining a point in 3D space.

Exceptions

NonZeroDivergence()	A class for handling the exception raised by passing in a magnetic field that violates the zero divergence constraint.
NullPointError	A class for handling the exceptions of the null point finder functionality.

Warnings

MultipleNullPointWarning	A class for handling the warning raised by passing in a magnetic field grid that may contain multiple null points in close proximity due to low resolution.
NullPointWarning	A class for handling the warnings of the null point finder functionality.

Functions

null_point_find([x_arr, y_arr, z_arr, ...])	Returns an array of NullPoint object, representing the null points of the given vector space.
trilinear_approx(vspace, cell)	Return a function whose input is a coordinate within a given grid cell and returns the trilinearly approximated vector value at that particular coordinate in that grid cell.
uniform_null_point_find(x_range, y_range, ...)	Return an array of NullPoint objects, representing the null points of the given vector space.
