Convert three yt keys to a mlab vector field

Parameters:

ds : yt dataset

The dataset to get the data from.

xkey, ykey, zkey : string

yt field names for the three vector components.

cube_slice : numpy slice

The array slice to crop the yt fields with.

SI_scale : float

Conversion factor to SI units (multipled by the field).

field_name : string

The mlab name for the field.

Returns:

field : mayavi vector field
