Since I have updated from Maple 2021 to 2023 something is wrong with my stylesheets.

I rephrase my qeustion here:

I like to change the text-style of 2D-Input to courant 12, bold, color x, no italic.

Now it is courant 12, black, italic when opening a new worksheet.

I was going to format, style, 2D-input, modify and then the font has changed when opening a new woksheet but the color is going back to black and its also italic courant when pressing enter in that worksheet.

I When opening a new worksheet, i don't want ot looad an new style set by hand every time.

Thanks for support

How will I use maple 2016 to solve ODEs and showing the steps involved because this will increase my understanding in it. 

The worksheet below includes a sample use of the Mobius transformation which produces a hyperbolic reflection of a point in the Poincare disk, followed by my attempt to produce the same result from first principles in a procedure.

Do I misunderstand the Mobius transformation and its use and/or is my procedure incorrect?

Is there a way to directly code a complex conjugate such as z with overbar without using the verbose conjugate(z)?

Soit h : [1 ; + ∞[ℝ

1.a°) Complète le tableau ci-dessus et trace la courbe ( Ch) de h dans un repére orthonormé ( O,I,j )

 𝑥 1 2 3 4 5

h(𝑥 )

b°) Montre que h est une bijection

c°) Détermine la bijection réciproque h-¹ de h

d°) Calcule hoh-¹ et h-¹oh ( 𝑥 )

2.) Trace la courbe ( Ch-¹) dans le même repére que ( Ch)

Hi,

I am looking for a simple code to generate random magic squares (with the sum of integers) of dimensions 4x4 or 5x5.

Thank you

I have a very simple question:

How do I find the index of an list element.

For example to find 96 in the following list which is the 25th element.

R := [1, 2, 4, 8, 16, 32, 64, 31, 62, 27, 54, 11, 22, 44, 88, 79, 61, 25, 50, 3, 6, 12, 24, 48, 96, 95, 93, 89, 81, 65, 33, 66, 35, 70, 43, 86, 75, 53, 9, 18, 36, 72, 47, 94, 91, 85, 73, 49];
max(R);
                               96

So how to find 25 ?

I have the following procedure

export exportCsvMatrix := proc(m:: Matrix, fileName: string)

  ExportMatrix(fileName, m, target=csv):

end:

However, I would like to be able to pass a list of matrices as well.

How can I add a parameter type that is Matrix or list of Matrix?

Good day to all the members who read this question.
I ask for your help to find the right way to solve this two differential equations (is attached the file). Used the common code "dsolve" but is not working on this problem. Doesn't matter if the solution is numeric or algebraic.
I will thaks a lot your kind help.
Best regards to all of you

I have a very difficult time finding things in the documentation.

I would like to see documentation for `<,>` and `<|>`, as in `<,>`(1,2,3,4).

If I write ?<|> in Maple I get

If I do ?<,> I get

However, there is no mention of the usage of the backticks.

Finally, if I do ?`<,>` I get

No mention of the use of `<,>`. I only know about this from a previous reply to one of my questions and now I have forgotten the details so I am trying to look it up but it's hard to find.

Dear Power Users, I tried to make a model in Maple but after several hours of struggling I need some help. Can someone tell me what I did wrong or explain to me what is the meaning of the maplemint comment on procedure (optimalisatie)? Thank you in advance.

Suppose I have a set of vectors, say S = {x+4, 3x-7}, a specific vector f = -5x + 10 and I would like to determine if f is an element of Span(S). By hand it's a rather simple process, check the consistency of the corresponding linear system. Is there a way to automate this in Maple? That is, define a vector space (using any finite vectors: polynomials, matrices, etc.) with some basis and check to see if a given element belongs to that space? Moreover, if it does belong, could we get the linear combination of the elements of the basis that produces the desired vector?

For the t output I need to show 1, 1.2, 1.4....2, my attempt is highlighted in green below

Can anyone assist please?

I have a lists within lists.  I needed to search for a specific element in the sub-list and need to extract each such sublist that has an element.

I am only familiar with the search tool. Could someone suggest a simple way to do this.

For example, I have the following.

s := [{f0(t, r) = 0, n(t) = n(t)}, {f0(t, r) = 0, n(t) = 0}, {f0(t, r) = 0, n(t) = 0}]

I need to extract the sublist that has n(t)=n(t) so only the first element of the list s.
