In the File menu,  the Export As dialog is missing. Only the default (.pdf) can be used; no .mpl or .tex)
The Save As dialog is incomplete (e.g. save to .mws).

Or, is the installation corrupted?

Exploring the Mapping of Vertical Lines under 𝑤 ...

Asked by: Paras31 230

April 10 2025
0  2

In the transformation w = e^z, vertical lines in the complex z-plane of the form Re(z)=a are mapped to circles of radius e^a in the w-plane.

Can I create a Maple visualization that does the following:

  1. Displays the result side by side, showing each vertical line in the z-plane and its corresponding mapped circle in the w-plane.

  2. Does it use a different color and style for each line and its image (e.g., dashed, dotted, solid, or different colors)?

This is first type of solving parameter but  i solved some semilar but the shape of them are so different and solving them different too i did my trail but i can't reach out solution also the author solve by another way which i did too but i have to solve in this way too thanks  for any help !

RGB Matrix for a 3D plot...

Asked by: Mapleliquid 20
April 10 2025

Dear community,

i want to create my own RGB Matrix for a plot. In this picture from maple soft homepage you can see a matrix A. I created a Matrix with 49 rows and 49 columns. From Datatyp Float. The plots is just red. Has anybody an idea how I can create a Matrix, which works?

Simultaneously solving showing error?...

I have two conditions, A and B, which must both be greater than or equal to zero. However, when I try to solve the problem, I encounter an error.

Could you please help me resolve this?

Note: All the parameters, whether specified or not, are positive and greater than zero.

Display quality with rotated screens...

I need to take up an issue which is quite old, but still unsolved.

https://www.mapleprimes.com/questions/234249-Text-Quality-On-Screen

The problem is that in specific display configurations with one (rotated) vertical screen and multiple horizontal screens, the quality of fonts especially is significantly lower in Maple as with a configuration with just horizontal screens.

The affect is visible in Maple when it is on the horizontal (unrotated) screens.

Here are screenshots for comparision, and the layout of my desktop.

Screen layout:

Screenshot rotated

Screenshot unrotated

It seems that the problem is present when starting Maple. Changing the rotation of the screen when Maple is running does not affect the font quality in Maple.

Other (Windows) programs are not affected at all of this changes, so this seems to be a Java issue.

How to get roman numbers in subscripts ...

Asked by: C_R 3347

For constants I prefer subscripts over indeces.

I noticed that numbers in subscripts are printed in italic. This is against a common prettyprint convention, where variables are in italic and numbers are in roman. In the example below "1" can easily be misread as "l" (which is probably one of the reasons for this convention)

Is there a way to get numbers printed in roman in subscripts? To force roman print I tried

t__`#mo("1");`
Error, missing operator or `;`

In 2d-Math the convention is respected in the input but not in the outut

Parameter Sensitivity and Conditions for Ensuring ...

Asked by: Andiguys 65
April 08 2025
0  0

I want both Pc and r(Pc) to be greater than or equal to zero. The only constraint is that all parameters for which I’ve provided data must remain positive. Can we identify the key parameters that significantly affect Pc? Also, what condition ensures that Pc ≥ 0? Ideally, I’d like Pc to be less than or equal to Pu. Could you suggest what changes in the numerical values I should make to ensure Pc becomes a positive value?

Attaching file: Q2.mw

Can we include a graph that shows how Pc changes with respect to variations in the most sensitive parameters?

With the new GUI:
I get all files (*.*) listed by default.
Other file types to filter are not listed.

Is this the same on other machines?

Can I do something about it?
