Need mapping toolbox mstruct for SCAR stereographic projection

I need to generate a mapping toolbox projection structure for the Scientific Committee for Antarctic Research (SCAR) standard projection. It is a polar stereographic projection with a standard parallel at 71S. None of the azimuthal projections accept standard parallels, so how do I calculate the scale factor I need to make -71 the latitude of true scale?

These don't completely answer your question, but at least will let you translate from the SCAR projection into one that Matlab does have.

See POLARSTEREO_INV

and POLARSTEREO_FWD
