for the record, I just discovered that while you can save a worksheet with a name like


you cannot open it (with Maple 15, June 2011)

Maple will return an error message like "file could not be found" (swallowing up the "mywork," part of the name)

but if you rename it

it will work fine.

In other words, do not insert commas in file names.

I do not know/remember if...

I'm learning to handle the output of pdsolve. It is a module and I'm quite new to that. The objective is to plot the solution for different values of, say, time t, in a fairly systematic way. I'll consign here my progress for reference. Feel free to comment if you have suggestions.

 sol := pdsolve
  ( diff(u(x, t), t) = (1/10)*(diff(u(x, t), x, x))
  , {u(0, t) = 0, u(x, 0) = 1, (D[1](u))(1, t) = 0}
  , numeric

This is for Spanish speakers only. Not related to Maple, but related to Math. The Spanish newspaper El Pais has a series of videos on various math problems, together with solutions (posted later), it's set up as a sort of competition but just watching is (usually) great fun. You can access the full archive online.

You probably don't need to know much Spanish to follow the problems. Much is illustrated in writing on a black or white board. If you don't speak any Spanish...

I'm posting here because between the time I started writing and the time I wanted to post my answer, the question is no longer available (may be a network problem, a withdrawn question, don't know)


The first problem is that you write ASAP in the title of your question, very uncool.

Another problem is that you use "else if" instead of elif, with "else if" you need one "end if" for each if but with elif you only need one "end if" to close the...

I just got a smartphone, amazing. Wouldn't it be wonderful to have a mapleprimes app to conveniently view and post messages from a smartphone or a smartpad or whatever? Any plans to set one up? (I'm on the android platform)

The other suggestion/question I have is: any plans (by Maple or others) to make a Maple calculator widget? I'm currently using RealCalc, which is great, but it  doesn't have the advanced term-grouping capabilities of the Maple calculator.
