We use matplotlib for plotting in python. We also have to convert SymPy matrices to NumPy arrays prior to plotting. Therefore, we prefer to define vectors as NumPy arrays if we intend to just plot ...

Assume that vectors A and B are position vectors. Create vector C so that C = B – A and can represent the displacement from A to B. Make sure it displays properly. You should be a vector master now.

When making this plot, typically you have at least one fits file: one with the polarization angles. If another fits file is included it has the polarized intensity or percent polarization. A couple of ...

The .quiver command in matplotlib.pyplot is for plotting many vectors all on the same set of coordinate axes. Much like .arrow it takes four inputs, the starting coordinates and the ending coordinates ...
