My ultimate goal is to plot multiple dipoles and superpose their field lines and create a contour. Currently i have used and edited a code that i have found on creating electric field lines on matlab, i have use two test points at set coordinates with set charges 1 1, yet the field lines that i get on my solution is incorrect. As expected, we have electric field lines coming out of the positive charge and into the negative charge. To launch the package of programs, at the matlab prompt type. How to add two vertical lines to plot and color between. It does not produce a plot of field lines of a vector field.
