Hello,
I am trying to model the electric fields and gradients between two wires. I have two lines (wires) on a plane. and would like to model something like this:
This has been done here: http://www.mathworks.com/matlabcentral/fileexchange/42773-electric-field-of-a-parallel-plate-capacitor-using-2d-poisson-equation
But I would like to try modelling it own my own. It would be helpful if anyone could point me to materials or examples that can help me model field lines and gradients between the two wires.

Three functions (that the code in the FEX submission uses) that would help are: contour, gradient, and quiver. The documentation for those contains examples on what they do and how to use them.
