inuctancies for wire loops by Maxim Vedenyov

calculates self inductance and mutual inductance (inductance, mutual inductance, wire)

L=inductance_neuman(x1,y1,z1,x2,y2,z2)

L=self_inductance(x,y,r)

[xr yr]=squares_in_polygon(x,y,ss)

wireframe by Daniel Ennis

This function plots a sub-sampled wireframe of a surface. (specialized, plotting, surf)

L=wireframe(X,Y,Z,N)
