Conversion routines to take a surface (a function z of (x,y) or (theta,r)) and convert this into a solid; much as meshz does, but a little more useful for outputting as an STL for frabrication in a 3D printer. There are two cases, one in Cartesian co-ordinates, and the other in polar...

Solves the mixed integer nonlinear problem:min p(x,y)s.t. f(x,y)

fieldlines3D(X,Y,Z,U,V,W,x0,y0,z0) plots a field line with the initial point P(x0,y0,z0).The matrices X,Y,Z,U,V,and W must all be the same size and contain corresponding position and field components.The function employs the 4th order Runge-Kutta method for solving numerically differential...

JSURF is similar in almost all respects to the standard SURF plot except that it admits a second matrix T of z-coordinates of size [m,n] that is used to plot over the base surface described by coordinates (x,y,z). JSURF(x,y,z,T) plots the 3D surface T onto the surface described by (x,y,z)....
