Hi,
Chris M. Thomasson can ask 100 more questions.
I will happily answer them. But maybe I should
make a Wiki to explain the ever same things:
But, I still don't know what you main goal is?
The goal is "Prolog inferencing"
Don't worry about it.ÿ There are several regulars here
who
ÿÿÿÿ don't
ÿÿÿÿÿÿÿÿÿÿ understand
that programming can be done for fun.
It has textures to work with in the pipeline.
I don't need textures for "Prolog inferencing"
98 more questions to go, don't give up!
Here in sci.math, as everyone knows, I'm gearing up for
/linear algebra/ for fun.ÿ Still waiting for DVDs because
I'm not in a hurry.ÿ The book /Linear Algebra Done Right/
is interesting, and I've yet to go through the other rec-
commendations.[1]
I'm curious if you've ever thought of doing OpenGL with Prolog?
Does that even work?
[1] I have no idea how this word is supposed to be hyphenated,
ÿÿÿÿ I just do it anyway, because I'm not an LLM.
Bye
Take care!
You might have good luck looking up reputable university programs
and seeing what textbooks they require, these days.
Or, you know, just buy old ones when the library retires
the old good ones.
How about Householder's "The Theory of Matrices in Numerical Analysis".
I have several books that have been rescued from libraries. Sometimes
even corporate libraries, but now forgot which specimen that was. One
of my priced collection is /Phigs and Phigs+, An Introduction to 3D
Computer Graphics/, by John W. Blake (1993) and I haven't read a lick
of it. Possibly never will.
Appending A has a Fortran 77 example, and Appending B has one in C.
I have therefore added comp.lang.fortran and comp.lang.c to the
discussion. Mostly because the regulars there annoy me. They know
who they are.
I took sci.physics.relativity out of the discussion, as I don't know
anything about relativity at all. A future followup can re-add it
if relativity affects this conversation.
Linear independence and linear spaces inevitably
get associated with vector spaces. There are much
simpler accounts though of reflections and rotations
about the determinantal and the singular and the decompositions
and the forms and the echelon forms and reduction with regards
to things like cumulants and orthogonants and the matroids,
vis-a-vis usual closed categories and so on.
The cumulants and orthogonants and so on are lesser-served
accounts of the earlier 20'th century, and determinantal analysis, while
the matroids are the a bit more obscure accounts of geometrizations with regards to matrices.
What "linear" even is is usually enough "linear is linear".
Generally considered "ordinary" if through substitution.
I have to admit, I understood some of those words.
I'm an anti-reductionist, yet though reduction is one
of the most usual results in closed categories, the
methods and techniques, point being closed categories
aren't allowed to close themselves, only being found so.
I'm on the other hand, pro-Gauss-Jordan reduction. I may even
try to code it in C on my own, instead of doing it the coward's
way and use Sage like a "normal" mathematician.
