I have a degree in Mathematics and Physics from the Danish University Aarhus, comparable to a masters degree with thesis - majoring in Mathematics. In 1991-92 I was a visting scholar at UCLA, Los Angeles, following graduate courses in Applied Mathematics. Since 1992 I have been a teacher in a high school (gymnasium) in Denmark. Special interests: Applied mathematics, graphics and popularizing Mathematics.

Dear Maple users

I am trying to simulate the distribution of Q-values (Karl Peason) in a Contingency table. In that regard I need to use a two dimensional iteration. It require quite a lot of time to perform the computations. Using the values below, it required 1.3 mio iterations and took about 5 minuttes on my computer. My question is if there are ways I can speed it up? It might be using different commands, which are executed faster, performing computations in the...

In a short Maple program I am dealing with a collection of random samples from a uniform distribution. My problem is that every time I call a procedure creating a sample, I get the exact same one! Every run needs a different seed. How do I get a new 'random' sample? I could probably let Maple create all from scratch calling the Sample command with a two-dimensional range, but this will requre a big memory ...

 

Here is part of my code:

My question is a bit vague, but I hope someone can point me in the correct direction for a solution anyway. A Maple Package was been defined and placed in the Lib folder in Maple 16. The package does contain a number of custom defined functions, say Cos(v) and Sin(v) - with a capital letter to distinguish them from the usual built-in functions in Maple. After having called the package using the with statement, the new function works well in the worksheet. It also works...

Dear Maple users

I think I got the answer once, but I don't remember: How do I plot a function, whoose values include units? In the plot below it succeeds partly. The plot is being displayed, but units not simplified. In other situations I simply get an error, although it should work. I guess it has to do with simplifying units ... I hope someone can point out how to do it ...

Dear Maple users

We are using Maple at our school. Usually activation with the Activation code works well if the computer has a good connection to the Internet. Our data instructor have however experienced a problem with two computers he cannot seem to solve. He is not able to activate Maple 16 on those computers. After a failure in activation he even reset the license.dat file. Maybe someone have an idea to how we can get those computers activated and what the problem...
