I am a new user. I have a worksheet and need to see how the the procs are being accessed as it does not look like they are being called and executed as I would expect. What is the most efficient way to debug and see the calling order of my Procs?


Thanks in advance,


How difficult is it to simulate gravitational influences and perturbing effects on celestial orbits with Maple? Could this syntax be altered without excessive changes to consider these aspects?

Are there somewhere worksheets to take a look at as an introduction and to see how such goals would be approached and implemented?

Maple is a scientific software based on Computational Algebraic System (SAC) which has enabled this work entirely solve applied to Civil Engineering, Mechanical and Mecatrónica.The present problems in education, research and engineering are developed with static work sheets ie coding used innecesaria.Maple proposed models are shown below with an innovative structure; with the method of graphics algorithms and embedded components; putting aside the traditional and obsolete syntax; using dynamic worksheets as viable and optimal solutions to interpret and explain problems Ingineering.Design Advanced Analysis Tools (Applied Mathematics) Sophisticated Applications (efficient algorithms) and Multiple deployment options (different styles); this allowed generate math apps (applications engineering); can be interactive on the internet without the need to have the software installed on our computer; This way our projects can be used with a vision of sustainability around the world. Resulting in the generation of data and curves; which in turn will help you make better decisions analytical and predictive modeling in manufacturing and 3D objects; which would lead to new patterns of contrasting solutions.

In a worksheet, I have defined several long procedures. In order to simplify my worksheet, I would like define thes procedures in a package so as to call theses procedures from the package. It should enable to improve the readability of my worksheet.

However, i have never make a custom package. Can you detail me the main steps so as to create a custom package ?

Thanks a lot for your help.


I'm trying to export a worksheet to Latex. I'm able to exprot it. But the long equations are not broken into multiple lines. I have used Mathlinebreaking width 5.0 inch in the export option. But it still does not work. I can see the linebreaking command (\\) in the tex file. But when I compile my latex code the pdf does not have any linebreak. The equation just overflows. Any help will be appreciated. 

Just starting some work on numerical engineering solutions by going through a workbook, which includes a Maple Document on CD (with one and several .mws files).

As I don't have acces to a Maple system, I downloaded Maple Player. However - Maple Player will only accept .mw and .mwz files(at least that shows up on 'FILE>OPEN'); so trying to open an .mws file results in - NOTHING. In your forum I found some information that .mwz is a nonpublic Maple format !?...... Now I don't see a way to work with PLAYER. Isn't PLAYER meant for exactly that scenario - sharing MAPLE worksheets ?

So - what to do ?

Thanks for some hint,







In order to improve the readability of a worksheet, I would like to insert in text lines the equations that I calculate after with a input maple.


Is it possible to add in a text line equations and symbols as we can make with Latex or MathType ? For example, i would be interested to write vectors in a text line.

Thank you for your help.


Is it possible to obtain a nice indentation with a automatic process? Do you have some tips on this subject?

My objective is to improve the indentation of my code so as to make my worksheet easier to read.

Thank you for your help.

I tried to load my document containing some notes, but then I got the message "There were problems during the loading process, Your worksheet may become incomplete", and as the message said my worksheet were incomplete. Is there a way to restore the document? I have tried following this and added the line it suggested:

But it didn't work.

I have attached the file.

Using worksheet, in 2015. I have an execution group, such as


>... another execution group


And want to copy all the code from the first group, using the mouse. Is there another way, other than having to move the mouse by hand and select all the code in order to copy it?  In Mathematica, I can right-click on the cell edge, and select copy. This copies the cell to the buffer, then one can paste the code somewhere else. In Maple, I could not duplicate this behaviour which is annoying when one wants to copy large amount of code.

I found that if I put the code in a "code edit region", ie., do insert->code edit region, then right-click inside the small window of the code edit region, the copy is enabled, so I can copy the whole region without manually select it first.

But this does not work outside the code edit region.

This is really weird.


Does any one see a "||" in the above? I do not. Then why Maple shows this:

r := cat("dsolve(",eq,",y(x))");


This is Maple 2015 on windows. Running in worksheet mode

Here is screen shot


This problem does not show up all the time. For example, this works ok:


No "||" added. The problem with all the above, is that I can't make it all as a string in the first example above. I am trying to make a string of   "dsolve(" + ode + "),y(x)"

Here is the display options


thank you

Dear all,


I am making a mpl file which looks like below:


font_size := thickness = 4, font = [bold, "TimesNewRoman", 30], labelfont = [bold, "TimesNewRoman", 30], axis[1] = [thickness = 3], axis[2] = [thickness = 3], captionfont = [bold, "TimesNewRoman", 30], legendstyle = [font = [bold, "TimesNewRoman", 30]];


I  export it as mpl, but when I want to read it in a worksheet, I get the error below:


Error, on line 1, syntax error, character `?` unexpected:
<?xml version="1.0" encoding="UTF-8"?>
Error, while reading ``/Users/..../font_size.mpl``


This is just a simple mpl, I get this error for all mpl s that I want to read!

Can somebody help me with this please? It is really annoying :(



I have a worksheet that makes 38 Mo. I find it a bit huge because my code is only composed by 20 code lines. I guess that Maple has saved a important volume of data which makes the file very heavy.

I would like to reduce the size of my worksheet so as to be able to send it to colleagues.

How can I remove all the data save in a file?

I find how to display only the inputs but the data in term of size seems to be still present.

Thanks a lot for your help

Hi guys,

I can not execute any command in worksheet. I even can't set a variable to a number. When I write some lines and hit enter, it does not respond in anyway. Basicly I can't enter anything it doesn't do anything. How cold I solve this?


I once opened Tools-Tutors-Precalculus-Polynomials. Now every time I click the button of 'execute the entire worksheet', the same Tutor  window will pop up before Maple executes my codes. I wanna know how to prevent the window to pop up?
