Is it possible to produce a file of something like tab delineated data via a 2D plot object? Basically all I want to do is create a data file using the points stored in the plot structure for use in a METAPOST file, and I haven't been able to come up with anything. Any help would be greatly appreciated. Thanks a lot. Keenan

I've just encountered a problem that I've never seen before, although I suspect I'm overlooking something very simple, and I was hoping to get clarification. In the course of defining a function I wanted to have a sum going over the indices of a vector; something like, sum(abs(x[i]-y[i])^2,i=1..3), and I receive "error, bad index into vector." This construct works fine with the seq command, so I'm not totally sure why it fails when using the sum command. Any ideas would be greatly appreciated. Thank you. Keenan

This may be something that has been addressed, and I'm certainly not insinuating anything is wrong with Maple; I'm just curious if anyone has any insight about this. Given a positive real number x, the sequence defined by a_n=([x]+[2x]+...+[nx])/n^2, where [x] denotes the greatest integer (or floor) function, converges to x/2, but Maple gives me 0 as the limit (could it have anything to do with the fact that n is not a continuous real variable; I tried assuming(n::integer) without luck). Any ideas? Thanks a lot. Keenan

I was wondering if anyone knew of any Latex environment(s) or configurations that could be used to simulate the look of Maple input (Classic Worksheet Mode). Any suggestions or ideas would be greatly appreciated. Thanks a lot. Keenan

I have had trouble figuring out how to specify initial and boundary conditions in pdsolve. I've tried using the syntax for dsolve, but without any success. I've also looked over the help page for the command but I can't seem to find any examples that illustrate this. Any help would be greatly appreciated. Thanks a lot. Keenan
