sphere_stereograph_test

sphere_stereograph_test, a MATLAB program which calls sphere_stereograph() to implement the standard stereographic mapping between the unit sphere and the plane Z=1, as well as a generalization of this mapping.

Source Code:

• sphere_stereograph_test.m calls all the tests.
• sphere_stereograph_test.sh runs all the tests.
• sphere_stereograph_test.txt the output file.

• sphere_stereograph_test01.m verifies that SPHERE_STEREOGRAPH and SPHERE_STEREOGRAPH_INVERSE are inverse functions of each other.
• sphere_stereograph_test02.m verifies that SPHERE_STEREOGRAPH is a special case of SPHERE_STEREOGRAPH2, and the same for the inverse function.
• sphere_stereograph_test03.m verifies that SPHERE_STEREOGRAPH2 and SPHERE_STEREOGRAPH2_INVERSE are inverse functions of each other.
