In ?property > Description it is stated:

A property can be:
...
(2) most types (this includes constant values, for example, 0)

E.g. I can do:

assume(x,1):
about(x);

Originally x, renamed x~:
  is assumed to be: 1

is(x,1);
                                    true

But, I am missing a useful example for such a property.

Besides, I find these properties confusing as 0 and 1 have parent properties entries in the property lattice, but not 2:

Can a procedure return separate plots?

Hi everyone,

Here is a problem that I couldn't solve:

I've written a procedure to perform some tasks, and I want it to plot some results as output, in addition to the equations of those plots (I don't think the details of the procedure are necessary at this stage, but I'll be happy to provide if needed). My problem is: Each procedure can only plot a single picture. I know Maple can plot several graphs in one plot region, but is it possible to do the converse?

For example:

This behaviour of 'assume' puzzles me ... 
and it needed some time to locate it
 
  restart; interface(version);

  assume(a::real); 
    #a:='a'; # activating removes the problem
  f0:=x+a; 
    #a:='a'; # that would not help - since is in use?
  assume(0<a);
  f:=collect(f0,x);

Watcom Compiler

Hello,

 

Whenever I use the compiler in Maple 12 ...I get an error message that it cannot create a directory becuase of write permissions.  I have opened up all permissions that I can think of.  Am I missing something ??

 

Thanks

recent posts link

It would be nice to have a link to Recent posts off the main mapleprimes page that guests see (ie. even when not logged in).

It'd be a pity if the only reason that this is not available is just so that page can show how many new (unread by logged-in user) posts there are in each thread.

Is there a way to customize a palette?

Hi-

I've been trying to figure out how I can customize a palette so that includes unicode characters that aren't included in any palette already.

I have a habit of using symbols from languages that aren't customary in the math world for some of my work. I use a lot of Japanese characters as well as some from various other languages.

I'm running into a problem with Maple where DotProduct seems to destroy the functions it assigns.

I ran a simple case, and it seemed to work just fine: (dotproductproblem.mw)

However, my code seems to follow the exact same logic but doesn't want to work? Code is a simple check that a bessel function solution of current density follows Maxwell's Equations. (Cylinder_AC_test2.mw)

Maple 11.

Has anyone encountered this problem before? Or know what's wrong in the code I'm running? (code attached)

Hi

I'm trying to work out how the Global Optimization Toolbox works and I thought I got it working. However, when I increase the ranges of the parameters over which the Toolbox should look for the solution (but still including the previous range), the outcome of the optimization changes, i.e. the toolbox finds different optimal parameter values and a different, and often higher, Sum of Squares (which is my evaluation criterium). I don't understand what I'm doing wrong!

An example:

I'm considering to buy an Asus Eee Pc 4G, but before I'd like to know if Maple 11 can smoothly run on it (at least with classic interface).
Is there somebody who has tried it?

Thank you!
