Electric dipole in MATLAB

I have to model few things such as electric dipole in MATLAB.(see below for question)

- Please give me advice approaching to this.
- IS it possible to use PDE tool in matlab directly.
if so How to do it.

example problem is here ;

potential V due to two equal charges that have the opposite sign and are
separated by a distance d in a vacuum.Using MATLAB, plot the equipotential contours and the electric field surrounding the charges.
