The Locator object is a nice piece of Mathematica's Manipulate command's functionality. Perhaps Maple's Explore command could do something as good.

Here below is a roughly laid out example, as a Worksheet. Of course, this is not...

Hi there

I'm a new user of Maple 15 and would really appreciate some tips on how to get started, this time more specifically on how to change the axis orientation. I'm a geotechnical engineer and in practice we always plot all the soil properties (strength, density, water content, etc) with depth, and so it should be positive downwards. 

I've seen a few posts where the issue was raised by some people years ago but was just curious to know if the new version...

Is it somehow possible to apply the Explore command to a procedure with numerical parameters?
It would be convenient in some cases. For example, let us consider  the following  procedure:
K := proc (alpha, theta1, theta2, sigma, n::posint)
uses Statistics;
t[alpha] := fsolve(CDF(RandomVariable(NormalDistribution(0, 1)), -t) = alpha, t);
 beta := evalf(CDF(RandomVariable(NormalDistribution(0, 1)),
t[alpha]-sqrt(n)*abs(theta2-theta1)/sigma));

The iPad is a very exciting device and it has been gaining broad adoption from our academic and professional customers alike. It was a logical step for us to bring Maple technology to this platform.
 
The Maple Player for iPad is now available in the Apple App Store. It comes bundled with ready-made interactive Maple documents, covering topics like integration, differentiation, computing...

Hi:

Is it possible to programatically specify which variables are to be skipped and what the ranges should be for others when using the Explore command? I mean as options to Explore.

If not, is this in the future plans?

thanks,

Hi,

I have explored some multi-animation with maple, but I can not change the parameters one by one.

Command Explore is analog to Mathematica's Manipulate but the problem in a new worksheet.

How to get Explore like Manipulate in the same worksheet ?

Hi,

I want to explore for example:

Explore(plot(Sum(i^2*sin(i*x), i = 1 .. n), x = 0 .. 10));

I know that animate can be applied as:

animate(plot, [Sum(i^2*sin(i*x), i = 1 .. n), x = 0 .. 10], n = 1 .. 10);

Is it possible to get the Exploration Assistant in the same worksheet after the command Explore and not in another worksheet ?

Explore can be done for many parameters which is not the case for animate.

Thanks for any suggestion

As I have recently learned, the environment variable 'Digits' controls the working precision and is therefore crucial for avoiding significant impacts of round-off error effects on floating point computations.

Moreover I discovered, that even when I set Digits to say 20, Explore is not affected.

Is there a way to control the working precision of the floating-point computations carried out by the Explore option?

Consider the following expression:

sCARA4 := -ln(-(mu/sigma^2)^(mu^2/(mu-sigma^2))*(sigma^2/mu)^(mu^2/(mu-sigma^2))+(sigma^2/mu)^(mu^2/(mu-sigma^2))*((exp(phi)*sigma^2+mu-sigma^2)*exp(-phi)/sigma^2)^(mu^2/(mu-sigma^2))+1)/phi;

Now try to find out whether the first derivative to mu is positive for all positive mu, phi and sigma, except for some rare exceptions (e.g. sigma^2=mu).

diff(%,mu);

Since 'is' is not a satisfying option, I used 'Explore'...

I tried to find out whether the expression

g1:=2*mu*(phi+ln(mu/(exp(phi)*sigma2-sigma2+mu)))/((-sigma2+mu)*phi)+mu*(1/(exp(phi)*sigma2-sigma2+mu)-mu/(exp(phi)*sigma2-sigma2+mu)^2)*(exp(phi)*sigma2-sigma2+mu)/((-sigma2+mu)*phi)-mu^2*(phi+ln(mu/(exp(phi)*sigma2-sigma2+mu)))/((-sigma2+mu)^2*phi);

is positive under the given assumptions:

         
is(signum(g1)=1) assuming mu>0, sigma2>0, phi>0, sigma2<>mu;

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...

Maple14 has an "explore" option by right-ckliking on an expression.

I did so with the following one:

and wanted to determine the frequency of the intermediate steps for the parameters.

E.g. p ranges...

Since the MRB constant is an alternating sum of positive integers to their own roots, f(n)=(-1)^n* n^(1/n); a thorough understanding of the changes in f, as n changes, is important.
In this blog we will begin to explore the derivative of f at integer values of n, and as n-> infinity. I am not sure weather this will help us in computing more digits of the MRB constant since we already know so many,

The appearance of this thread has degraded over the years, but most all post about the MRB constant can be found by entering "MRB constant" into the search box.
