I therfore have avoided matrix analysis, even though it obviously, in a given case, would make a very nice short-cut.

(Especially with computers: Other modalities can be technically more difficult to set up, even with, say, Mathematica).

I'm primarily in "Physics," but math is ,of course, integral. My math has always been crippled via the above.

Any "solutions" suggested?

Thanks, Rudy
