The Standard GUI has an option (Tools -> Options -> General -> Browser) for configuring an installed web browser.  The GUI uses that for its own purposes (for example, clicking on an error message opens the browser at a related Maplesoft site).  Is it possible for the user to access the configured web browser from within Maple, using Maple code?

I have been using Maple in Document mode to provide documentation of engineering calculations according to various design standards.

I have been asked to provide more detail about certain critical calculations.

Ideally, I would want to enter the formula as a symbolic espression, then the output would begin with and echo of the expression with numberic values substituted for the variable names (ie without performing any mathematical operations), and then give the evaluated answer.

I am solving ode system in double precesion with digits 16, some results are in power of -16 which are equivalent to zero. How can I ask maple to put any number with the power of -16 or less to be zero?

Thx for the help.

Hello there!

I'm looking for some help with my maple code ^^

Here's the problem:

I have 2 Arrays, A and B. A is an array of points each with its own x and y coordinate ( [[1,3],[5,4],[4,5],...] ) array B is an array of values ( [0.5,0.2,0.1,0.6,.....] ). My goal here is to plot with a dot on each of the coordinates in A with a circle around them of radius of the corresponding value in B. ( the first point [1,3] will be printed on the graph as well as a circle of radius 0.5 ...

I think this is a simple question.  I have a gear train that has an input rad/s and an output rad/s.  I need the output speed graph to read in mm/s.  Basically I just need to multiply the rad/s by 2(Pi) to get rps and then multiply the rps by 2(pi)r to get mm/s.

I'm a university student trying to solve a problem, we've been given a very little maplesim knowledge, mostly gear related.  If someone can help me make a custom probes or plots that would be appreciated.

Hi everyone,

I am importing an .m file from MATLAB to Maple using the command: FromMFile(). The .m file uses a set of huge symbolic matrices with an output of a huge symbolic vector of 36 by 1. Each element of this vecot is supposed to form a second-order differential /or algebraic equation that I am planning to solve using the Maple DAE toolbox.

The problem I have is that while I execute the worksheet, Maple only evaluates the...

I have a system of equations:

> c := .67;
print(`output redirected...`); # input placeholder
                                    0.67
> r := `<,>`(r1, r2, r3);
print(`output redirected...`); # input placeholder
                       Vector[column](%id = 190246956)
> Y := `<,>`(gamma1(t), gamma2(t), gamma3(t));
print(`output redirected...`); # input placeholder
                       Vector[column](%id = 190247020)
> r1 := piecewise(gamma3(t...

I solved the following system using fourth order finite difference and shooting methed and i obtained the results below

but when i tried to solve it using dsolve in Maple I did not obtain the accuract results, I hope to know how to obtain accurate results with this system(the system is uploaded)

 restart; Pr := .72; a := 1; c := 1; lambda := 1; M := .2; lambda1 := .2; beta := 0; Ec := 0; A := 0; B := 0; R := 0;

sys := diff(f(t), `$`(t, 3...

Can someone please help me with the Maple language in solving the following equations?  I have already solved them by hand but I am new to Maple and am having difficulty with the coding language.  Here are the problems:

1.  Graph the parametric curve x=2t-pi*sin(t), y=2-pi*cos(t) from 0 to 20.  The curve forms loops, determine the arc length of one loop. 

2.  Graph the rose curve r=sin(4theta) in polar coordinates.  Determine the area of one pedal. 

Ok, first of all I renamed the return matrix R (A is allready used)
I now think I got two of them (minimize portfolio variance and minimize portfolio variance for a
given expected return in matrix form) figured out:


Cov := Matrix(CovarianceMatrix(R), datatype = float):
pr := .6*max([seq(ExpectedValue(Column(R, i)), i = 1 .. nstock)]):

A := Matrix([[seq(1, i = 1 .. nstock)]], datatype = float):
b := Vector([1], datatype = float):
Aeq := Matrix(...

How to make maple notify about calculated stage in example? As you can see fprintf+fflush doesnt work (hope stdout in maple has descriptor 0 as in others)...

eval_stage.mw

P.S. Don't wait procedure done. Just interrupt.

Hi im new to maple and i need help. I have 2 Matrix, and want to calculate the  angles. I tried very different functions, but i dont get forward.

Did anyone can help me by my problem.

For example:

MAtrix A: 0,999     |    0,012  |-0,002

             -0,012    |   0,975   |-0,218

     ...

I have some data which have a binary tree structure.

Is there a simple way to plot (at least partially) my binary tree?

How can I specify the step size in solving complex system of ordinary differential equations using RK45 with dsolve command???

Thanks,

Hi,

How can I model a ground pattern, like was done in the demos of the planetary rover (http://www.maplesoft.com/products/maplesim/demo/OrangWowMoment.aspx)?

I see in the block model of the planetary rover that there is a component called "ground pattern" and it is not connected to any of the other components of the model, and this component is also not part of any default libraries of Maplesim.
