I recently realized that maple/standard has some plotting capabilities not available in maple/classic. I nevertheless plan to stick with classic except for the occasional printing of graphs. I don't want to write multiple worksheets, so I want my worksheet to know when I'm printing in standard and when I'm printing in classic. I don't want a maple/classic plot to overwrite a maple/standard plot (and vice versa). I want to set some classic-specific and standard-specific options.

I have an issue where in standard interface Maple won't display the extra digits.  As an example evalf(10.5) returns 10.5 only. 

We are conducting a survey about Maple's user interface, and we want to hear from you.  There are 25 questions and it should take no more then 10-15 minutes to complete.  As a thank you for taking the survey, 5 lucky participants will be chosen at random and will receive a Maplesoft shirt (to be eligible for the shirt, you must fill in the optional contact information).

You can find the survey here.

Thanks in advance!

I am trying to model reflectivity data at a Mn-doped GaAs interface and hence I need to create a Kramers-Kronig Transform to determine the depth-dependent complex value of the index of refraction at specific beam energies.  The integral I am trying to solve is the following:
f[1](omega) = P(2/(Pi)*(∫)[0]^(infinity)(u*f[2](u))/(u^(2) - omega^(2))du),

When I plot(cos(2*x^2)) the plot doesn't look right.  The graph area between -7 and -8 jumps and similarily on the positive x-axis.  It doesn't appear to affect values just the visualization of graphs.  If you plot(cos(2*x^2),x=-7..-8) the graph is fine. 

As a follow-up to the original post, I thought I’d mention a few of the additional new features particular to math education. For more information, visit the What’s New section of the website.

I would like to save the output of a plot structure (resulting graph) or a combination of multiple plots (using display[list]) into a PNG or postscript file from within a procedure. I have managed to successfully save a plot in one of the graphics format using this approach (Pseudo-Code):

Hello all, I am running maple 12, linux version. I was wondering, if using the command line version instead of the graphic Java interface makes any difference in speed (when running very 'hard' algorithms, which are likely to run for several days). Thanks in advance. George

I am not sure where is the proper place to report the following bug.

input:
version(); interface(version); kernelopts(version);
u[1] := proc (t) options operator, arrow; 1+2*t+3*t^2+4*t^3+t^4+t^5+t^6+t^7+t^8+t^9+t^10 end proc;
u[2] := proc (t) options operator, arrow; t end proc;
save u, "/home/user/test.txt";
restart; read "/home/user/test.txt";

output:
User Interface: 277223
         Kernel: 277223

<p>How do I force values to be shown in scientific notation in a spreadsheet? The Format:Numeric Formatting ... menu selection seems to have no effect in this case. I also can find no option (ie hfloat) or interface parameter (ie Digits) that can be run within a function that will "massage" numbers to be scientific notation.</p>

I've recently updated to Maple 12 (on Mac OS X.4.11) and am still learning how to use it. A search on Maple FAQs didn't turn up any answers to the following questions.

Hi,

I am a relatively new user of Maple, and I try to solve numerically the following PDE system :

> pde01 := diff(c(z, t), t) = (diff(c(z, t), z, z))-(diff(c(z, t), z))+k*(a-c(z, t));

> pde02 := diff(b(z, t), t) = (diff(b(z, t), z, z))-(diff(b(z, t), z))+k*(a-b(z, t));

> cl1 := c(0, t) = piecewise(t <= 0.3, 100, 0.3 < t and t <=0 .5, 200, 0.5 < t, 100);

> cl2 := c(l, t) = b(l, t);

> cl3 := (D[1](c))(l, t) = (D[1](b))(l, t);

> cl4 := b(L, t) = a;

  I been trying to run a maple loop recently where maple computes the values of r,theta,phi for spherical coordinates from some fsolve statements. However I have found this to take an extremely long time (days). What I want is for it to make rows of these and then output them to a file so that I have rows of r,theta and phi for several hundred thousand of them atleast. Currently I simply create a n by 3 array with however many entries my loop has and then fill each position in the array using for loops then I use writedata to write the entire array into a file.

I wonder what virtue there would be in an "assistant" in the Standard GUI to show and allow control of the interface settings.

In the absence of a built-in assistant (or tab in the Tools->Options panels) I wonder whether a simple Maplet would serve.

In a previous post I described how to call OpenMaple from a C# application (see: Using OpenMaple with C#) Now, I'd like to tackle the reverse problem: how do I call a C# .dll from within Maple? The way to do this involves using Component Object Model (COM) interoperability in the Microsoft .NET Framework. Because Maple's kernel is written in an "unmanaged" language, a wrapper is needed in order to bridge to your managed C# code. This article will outline the steps needed to create this bridge and get Maple talking to C#.
