Electrostatic Fields

These are a collection of Octave scripts to visualise the electric field due to a system of point charges

• plot electric field lines [field_lines.m][link1]
• plot the normalised field vectors 2D version [field.m][link2]
• plot the normalised field vectors,3D version [field.m][link3]
