What homogeneous transformation matrix will duplicate the 2D projection made by plot3 when using its default orthographic projection, having rotated the plot in 3D, and when I have retrieved [az,el]=view() after using plot3?

What homogeneous transformation matrix will duplicate the 2D projection made by plot3 when using its default orthographic projection, having rotated the plot in 3D, and when I have retrieved [az,el]=view() after using plot3?

Although I know an orthographic projection is used, that is like a 5 star chef saying add cheese to a recipe, and expecting the listener to divine a specific kind of cheeze. Orthographic projections are not a specific projection matrix, but a family of families of projections, since axonometric projections are a subclass of orthographic, and [ trimetric, dimetric, military ] are subclasses of axonometric.

I need to know the specific transformation matrix applied so I can duplicate the projection in 2D exactly. Only then can I computte a score for how well the projected data is clustering (a subgoal for a machine learning process)..

Help!
