I have been investigating Predator-Prey spatial models, e.g.

diff(N(x, t), t) = r*N(x, t)*(1-N(x, t)/K(x, t))-a*N(x, t)*P(x, t)+d[1]*(diff(N(x, t), x, x))

diff(P(x, t), t) = P(x, t)*(b*N(x, t)-c)+d[2]*(diff(P(x, t), x, x))

 

Hello all,

I've noticed that something has changed to the type of sqrt in Maple 15, which breaks backward compatibility...

In Maple 14, we have

> type(sqrt,procedure);          true
> type(sqrt,`module`);          false
> eval(sqrt);          proc(x::algebraic, f::identical(symbolic))  ...  end proc

while in Maple 15, we have

> type(sqrt,procedure);          false
> type(sqrt,`module`);          true

I am a mechanical engineering graduate student and I use Maple daily for everything from school projects to homework. Unfortunately, printing anything out (to hand in) either (a) ends up looking absolutely terrible / enormous or (b) takes forever to format. I have to go through and apply all of these styles I've saved that make all of the fonts smaller and a different color (and when I do that, things look weird.... powers are impinging on their bases [e.g. the x and 3 in x^3 are fused...

I have a worksheet that contains various pieces of a robot's dynamic and kinematic equations.  I want to perform different design tasks, taking the base model and working off of it.  I'd like to have only 1 model of the robot and not duplicate it across all of my different design worksheets because things change in the robot model as I switch up tooling, find better means of performing a system identification, etc.

Is there any functionality that would allow...

Hello,

 

I have 3 points:

A:=<a,b,c>;

B:=<e,f,g>;

C:=<h,i,j>;

Please show me what is wrong: plane(p1,[A,B,C],[x,y,z])

how to make a plane with these points.

error: Error, (in geom3d:-Equation) wrong type of argument

Thanks a lot!

Currently, using Explore results in a new worksheet which contains all the sliders and output components.

And there is code, which makes it all "work", that gets hidden in that new worksheet. But It's very awkward to copy those Components back to the original worksheet, because of the disassociation with the working code.

If, instead of having dependent code be hidden in that new worksheet in collapsed Document blocks, all the working code were instead inlined...

What single change in Maple would you want more than any other?

Maybe it's an enhancement, or a functionality change, or a bug fix.

Maple's Standard GUI has context-sensitive menus. Those are the menus that appear when one right-clicks on a output (or input, in a Dcoument).

Those context-menus can be customized.

Below is an example which adds a new submenu. The new submenu is populated automatically according to the types of thing found within the object itself.

It's an alternative to a menu-item that already exists, which shows up as "Help on Command". But that existing item only...

There are a number of facilities in Maple which may be extended. Included amongst those are `type`, `print`, `evalf`, and `latex`. The help-page ?extension_mechanism claims that all the built-in functions allow for extension. It also mentions a few system Library routines such as `verify` (but does not mention `latex`).

There are some descriptions of varying completeness in a few...
