Thank you!
\_ worked in Math mode.
I don't see 1D mode in the dropdown list.
I find that these various modes don't tend
to "stick". I type in one mode. Then, depending
upon what I type, I am automatically
flipped to another mode.
So, I don't even bother to notice what
mode I'm in.

Dear Georgios Kokovidis & Scott03,
Thank you for your help. I will try your
suggestions.
I never heard of "2-D mode" nor "1-D mode".
Nor of the "GUI interface" nor the "classic
interface". I do not know what any of those
terms mean.
When I bought and downloaded Maple, I just
thrust myself into a maze of help menus to try to
figure things out.

Oops! Sorry, I've not checked in recently!
I will look for your messages now.
I am not aware of all the different
directories on Mapleprimes. I tend just to
go to the same ones, namely, the recent posts
folder, over and over again.

Thank you, John Fredsted!

Thank you, John Fredsted!

I successfully figured out the rest of my
problem on my own, but I owe it to your
help. May I acknowledge your help in my
published paper?

I should have put up my ACTUAL problem on which I am working
since it is much more complicated than
the made-up thing I threw up here before.
I need to form an 8x9 matrix in which one
row consists of the following entries
alpha*(diff(diff(x^alpha+(x+1)^beta, x), x));
beta*(diff(diff(x^alpha+(x+1)^beta, x), x));
alpha*(diff(x^alpha+(x+1)^beta, x));
alpha^2*(diff(x^alpha+(x+1)^beta, x));
beta*(diff(x^alpha+(x+1)^beta, x));
beta^2*(diff(x^alpha+(x+1)^beta, x));
alpha*beta*(x^alpha+(x+1)^beta);
alpha*beta^2*(x^alpha+(x+1)^beta);
alpha^2*beta*(x^alpha+(x+1)^beta);
and the 8 rows are generated by substituting
in 8 different small integer values for the
pair (alpha, beta). Say,
(1,1) (1,2) (1,3) (1,4) (2,1) (2,2) (2,3) (2,4)
Then, afterwards, I need to compute the 9
8x8 minors of this matrix, and factor out
any common polynomials in x.
If these 9 minors are all zero, then I have
to go back and choose a different set of 8 values
for (alpha, beta), say
(1,1) (1,2) (1,3) (2,1) (2,2) (2,3) (3,1) (3,2)
but it is more likely I won't get all zeroes for the
minors.

Thank you for showing me this Maple matrix
constructor.
The example I threw up on this post had
no meaning. I just used it to ask the
question.

Yes, I have this paper. It references my doctoral dissertation, my one paper
published in the Journal of Differential Equations, and one of my four papers
published in the International Journal of Mathematics and Mathematical Sciences.
This ISSAC2007 paper is well written and very informative.

Thank you, Scott03, for pointing JacquesC into the right direction!
