mpas_tools.transects.Vector

class mpas_tools.transects.Vector(x, y, z)

A class for representing Cartesian vectors with x, y and z components that are either float or numpy.array objects of identical size.

Variables:

• x (float or numpy.ndarray) – The x component(s)

• y (float or numpy.ndarray) – The y component(s)

• z (float or numpy.ndarray) – The z component(s)

__init__(x, y, z)

A class for representing Cartesian vectors with x, y and z components that are either float or numpy.array objects of identical size.

Parameters:

• x (float or numpy.ndarray) – The x component(s)

• y (float or numpy.ndarray) – The y component(s)

• z (float or numpy.ndarray) – The z component(s)

Methods
