Why when going to user pages and clicking to see the next page, Mapleprimes gives

This happens for each page after the first one which shows OK.

Do others see this also?

I do not use table data struct in Maple and could not find anything in help on how to do this.

given a table T such as the following, typing indices(T) shows there are more than entry in each index

indices(T)

[[-0.687272727272727, -0.687272727272727, 1.],   [2.25818181818182, 2.25818181818182, 1.]], 

  [[-2.47, -1.47, 2.], [0.53, 1.53, 2.]], 

  [[0.245, -2.755, -2.], [2.745, -0.255, -2.]], 

  [[-2.6, -0.6, 3.], [0.379, 2.379, 3.]], 

  [[2.659, -1.341, -3.], [4.652, 0.652000000000001, -3.]], 

  [[-3.178, 0.822000000000001, 5.], [-1.185, 2.815, 5.]], 

  [[0.0672727272727271, -0.932727272727273, 0.], [3.06181818181818, 2.06181818181818, 0.]], 

  [[2.8895, -2.1105, -4.], [4.3895, -0.6105, -4.]], 

  [[1.01, -0.99, -1.], [4.02571428571429, 2.02571428571429, -1.]], 

  [[-3.63, -0.63, 4.], [-1.13875, 1.86125, 4.]]

In the above each entry in table has 2 indices. I want to keep only the first index in each entry so that it has only one, to become this

[[-0.687272727272727, -0.687272727272727, 1.]], 

[[-2.47, -1.47, 2.]], 

[[0.245, -2.755, -2.]],

 [[-2.6, -0.6, 3.]], 

[[2.659, -1.341, -3.]],

 [[-3.178, 0.822000000000001, 5.]],

 [[0.0672727272727271, -0.932727272727273, 0.]], 

[[2.8895, -2.1105, -4.]], 

[[1.01, -0.99, -1.]], 

[[-3.63, -0.63, 4.]]

And keep everything else as in in the Table. Just need to adjust the indices to be one entry instead of 2 or more.

Here is an example of such table

T:=table([([-.687272727272727, -.687272727272727, 1.], [2.25818181818182, 2.258181\

25490,.20392157,.18823529)])

Is it possible to do this in code?

Maple 2025.2

I am not able to find place in help which lists which changes interface(typesetting = extended); makes compared to interface(typesetting = standard);

Reason  I am asking, is that in interface(typesetting = extended); Maple adds a small annoying "dot"  between each term for multiplication, which is not there in standard.

Is there a place in documentation that mentions this as part of extended? Where to find it?

in Matlab and Mathematica it is possible to put the labels in contour plot, directly on the lines (with nice positioning).

This makes it much much easier to see the level of each contour line since the values are on the lines,  without having to jump to the legend and guess the color and try to visually match colors with the plot.

For example, in Matlab

clear; close all;
x = 0:0.05:20;
y = 0:0.05:15;
[x,y] = meshgrid(x,y);
z = (11-x-y).^2 + (1+x+10*y-x.*y).^2;
[C,h] =contour(x,y,z,10);
clabel(C,h)

gives

In Maple

f:=(11 - x - y)^2 + (1 + x + 10*y - x*y)^2:
plots:-contourplot(f, x=0..20, y=0..15,
         legend=true,
         contours=10,
         'axes'='boxed',
         legendstyle=[location=right], 
         colorscheme="DivergeRainbow");

Is there a way to tell Maple to put contour labels on the "middle" of the level lines (contour lines) similar to what Matlab does?

I see no such option in https://www.maplesoft.com/support/help/maple/view.aspx?path=plots/contourplot

I think I remeber doing this before but not sure and it is not in my cheat sheet.

Given an expression, I wanted to find all names in it. Which can be done using indets(f,name);

But then how to check if any of the names found are not in the Maple initial known names given in https://www.maplesoft.com/support/help/Maple/view.aspx?path=initialconstants

For example,

f:=x^2 - y^2+Pi;
indets(f,name);

Gives {Pi, x, y}  how does one then check if this list does not have any known name in it?

In this case Pi. I do not want to check explicitly for each name listed on the web page above.

Are these initial known names  grouped in some specific maple type that can be used to check against?

Or is there a command in Maple to return a list of all these initially known names? If so this list can be used to check against.

Asked google AI and it did not know.
