makestereofig is a standalone scr ipt for converting .fig files containing 3D Cartesian plots of z as a function of x and y to .jpg images of the same plot in anaglyphic (red-cyan) stereo. The compressed archive contains the top level scr ipt (makestereofig), an ancillary function (plotdisplay2), and a demo .fig file containing a plot of data and a fitting function. The algorithm is very simple and users are encouraged to tweak!
