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. John
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. John

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? resolvent

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!
