Hi, I need to construct a heap using a list. Have found this in Maple help. > h := (heap[new])(lexorder, greg, tony, bruno, michael); (heap[insert])(stefan, h); stefan > (heap[size])(h); 5 > (heap[max])(h); tony > while `not`((heap[empty])(h)) do (heap[extract])(h) end do; tony stefan michael greg bruno

I encounter a situation demonstrated in the following piece of codes:

I'm playing around with the embedded components, mostly buttons, sliders, labels, and plots.

Is it possible to include special characters such as omega or pi or beta on the label, or as the text on a button, or in the legend name of a plot? If so, how?

 

 

I want to generate a set of numbers of fixed size with maple, when I use the rand procedure within a fixed integer range let us say rand(1..2^4) and ask maple to pick 8 integers, maple will pick 8 different integers in the required range.

I would be grateful for any help.

Hi,

I have defined my group in maple as

G:=grelgroup({u,v,w},{[u,v,u,1/w],[v,u,v,1/w],[u,u],[v,v],[w,w]})

I now want to define a function on GxGxG. Previously I have used array, i.e. f:=array(0..2,0..3,0..4), but how do I do it for elements in G?

Many thanks,

Jenny

Using the typeset() plot option, I am interested in printing labels of vectors on Maple graphics. The vector labels must have arrows on top. I can do this already if I know the name of the vector in advance, e.g. "V", by invoking the command plots[textplot]([x, y, typeset(`#mover(mi( "V" ),mo("→"))`)]);

 

Hello all,

For a project of groundwater contaminations i need to plot the following graph.

18^2-y^2 = Q*(ln((3000*(18-y))*sqrt(0.412e-4))-ln(sqrt(x)))/(0.412e-4*Pi)

where as X stands for the distance of a waterfilter and Y stands for the water level.

I tried to plot this with maple but i cant find the solution for this.

 

Thanks for your time,

Gertjan

 

I got my 8 coordonates, I wanna plot a cube. When I all my coords in pointplot3d, it connects p1 to p2 to p3 ..to p8 so it doesn't make a cube. How do I make it so it connects the coords I want to make the cube. Thank you

Hi:

Concerning Maple 12 I note the following behavior:

cos(alpha-beta) displays as typed

cos(beta-alpha) displays as cos(alpha-beta)

Similarly,

sin(beta-alpha) is displayed as -sin(alpha-beta)

Anyone knows the xplanation for that and possibly how to prevent it from happening?

thanks a lot.

  See the interactive Level Curves and Cross Sections video tutorial: (Ctrl+click on link) Video Tutorial: Level Curves and Cross Sections   Alternatively, you can view a worksheet that provides a review and an example of level curves and cross sections.  

Kernelopts(multithreaded) returns true for both my P4 hyper thread processor (which is fine) and also my P3 tecra 8100 laptop. huh?

Isn't multithread only supposed to return true if there is hyperthread technology on the chip or the processor was dual core or dual processor.  Why is it returning true on my laptop P3 single processor? 

In order to optimize a large number of datasets I integrated the GlobalSolve command from the OptimizationToolbox
in a for loop. The code (in short form) looks like this:

for i from  1 to 100 do
data(i):= "read data from external file":
Z:= "function to optimize based on data(i)":
with(GlobalOptimization):
infolevel(GlobalOptimization):=4
B:=GlobalSolve(Z, a=0..2, b=0..2, c=0..2, timelimit=6000):
->Solution of optimization is exported to external file
end do:

How do I graph multiple functions on the same plot, and possibly with different colors for each line. Thanks in advance.
