A question about the "Explore" command...

Maple 2015

Greetings!

Strange things happen with the "Explore" command! Let's say I want to plot the function F(x)= a*x. When I am writing:

>Explore(plot(a*x,x=0..10),parameters=[a=0..2]) ;

everything is OK, but when I use:

>F:=a*x;
>Explore(plot(F,x=0..10),parameters=[a=0..2]) ;

the initial frame is correct but when I try to move the parameter cursor, the plot dissapears.

Any ideas what is wrong and how I can fix this?

Can I make a circular list or a set?...

Maple 18

Greetings to all,

I want to make a "circular" list but I cannot find a way.

To be more precise, let K=[x1,x2,x3,x4], is any way to set K[0]:=K[4] and K[5]:=K[1]?

Thanx a lot,

Explore command and Classic Worksheet...

Maple

Greetings!

I only recently started to work with Maple17 and tried to test the Explore command. In Classic worksheet I tried a very simple function with a parameter, but after setting the inteval of the parameter in the Java pop-up window I have no result. In return I take: "Error, (in Explore) invalid input: rtable_dims uses a 1st argument, A (of type rtable), which is missing"

Has anyone encounter the same issue before?

Thanx

How to draw Columngraph 3d?...

Maple 13

Hello to all,

I have some data and i want to create a 3d columngraph from them but i can't  find a relative command in Maple.. I want something like the "AreaChart" command without the lines connecting the points..One solution is the Pointplot 3d, but if there is a way to do it with columns is much more preferable..!

Thanx!

"Error, (in pdsolve/numeric/xprofile)"...

Maple

Hello!

I am solving numerically a non-linear Pde using the command  "pds:=pdsolve(....)"  and all are as they should be...[ pds := module ()...] but when i am trying to plot the outcome i receive: "Error, (in pdsolve/numeric/xprofile) unable to compute solution for t>.188000000000000000:Newton iteration is not converging "

Is there a way to overcome this problem (even if i must lose in accuracy..)???

Thanks!
