I don't recall ever changing any settings in my copy of Maple 16. But for some reason, I tried to make a plot and it spit out line-printed output rather than a regular plot.

How do I change this back? I have no use for line-printed output.

plot([E1(x), E2(x), E3(x)], x = 0 .. 5, title = "Nitrogen Nucleus Second-Order Energy Shifts")

I am looking for persons with experience in setting up maple for the blind. The setting is a 21-year old blind
 student who wants to do math. He uses Mac OS/X and the built-in VoiceOver screen reader, plus refreshable Braille display (one-line), a Braille printer, and Nemeth, the Braille extension for math symbols.

Initially, we are working from no experience whatsoever, trying ideas, mostly failure. Getting some advice from persons who are blind and using maple would be wonderful. If anyone knows of an instance, a person who is blind and regularly uses maple, then we would both would be delighted to receive advice on what to install, how to set it up, and how to use maple on a daily basis.

One trouble for the VoiceOver screen reader is verbosity of maple output. Any methods to reduce the amount of output would be welcome. To uderstand the issue, look at the output of these two commands when interface(prettyprint=0) has been set to help out the VoiceOver screen reader:

matrix([[1,2],6,7]]); Matrix([[1,2],[6,7]]);

The first outputs the same text, which VoiceOver will read accurately. The second dumps out two lines of extraneous and confusing information, only 20% of which is useful. The verbosity is not restricted to matrix packages linalg or LinearAlgebra. It is a problem wtih nearly all packages.

I'm having trouble scaling Maple 16 to be usable on a QHD+ resolution 13" screen. I was wondering if anyone know if it's possible to scale the interface of Maple through some option or if there is another trick to fix it.

Thanks in advance!

I recently got a laptop with an HD display (2560x1440).

While I can make the maple intput (and 2D math output) big enoght via zooming (ctrl+<number>), the default plots are unusable (everything is too small). This is true for "widges" created with Explore as well.

Has anyone come across this? If so how do you deal wit this problem? 

It would be nice if Maple could scale it's interface and default sizes of various elements properly for HD displays.

Ok i have used a diverse range of programming IDE now, but i am of course alot more comfortable the maple interface simply because of the amount of time i have spent on it, also it was my first "real" introduction to programming, but i was keen to trial and review of all the major CAS out on the market, but for a common purposed package within them they provide, for example the number theory package.


So the question is quite broad, im looking for suggestions for the most unbias way to go about this.

it would need to be a coauthored review with a representative writer for the seasoned user for each one right?

what would i write if i wanted to display the full list of variables that be specified by calling kernelopts? like as output in the interface, i naively attempted ops(kernelopts)  which didnt work of course.

#Hello people in Mapleprimes,




#shows f'(x).



#shows just df(t1)/dt1, not f'(t).

#Can't I show f'(t1) not df(t1)/dt1?

#Is this a way peculiar to Maple?

#I hope someone could give me some hints.


#Best wishes.






This is a specific Maple 2016 question: I find that plots no longer remember their attributes (like size on the screen) upon re-execution of a worksheet, even though I have set the appropriate flag in the Interface pane of the preferences.

Can someone confirm this; or am I just being dense? Is this an OS X issue? An El Capitan issue?? Maple 2015 on Yosemite behaves as expected.

Maple 2016.1 on Mac OS X 10.11.5.



i work on Maple 18 and recently maple standard worksheet interface not run properly.

i already have  uninstall and again i have same problems

Dear Forum, 


I am a new Maple user, and its symbolic prowess is really amazing. So we are trying to interface it with a C library. I want to generate some C code through Maple, and am trying the CodeGeneration package. 

But the default conversion of C(a, b) is b = C language equivalent of expression a.

Now this should be fine for most purposes, but the C library that we are working with, "ACADOToolkit" in this case, requires the equations to be formatted in a certain way. So, I need the following equation in C:


f << dot(v) == (u-0.2*v*v)/m


Now the LHS part of == is to be hard-coded, but we want to generate the equation on the right using maple. Even if I define an equation as 

eq1:= diff(v(t),t)=(u(t)-0.2*v(t)*v(t))/m(t) and then use C(rhs(eq1)), I get the result in the form of cg = u - 0.2 ...., whereas I want this to be assigned to something else, in this case - "f << dot(v)= ".


How can I achieve this ?

Why the interface typesettings option doesn't affect the content of a MathContainer?

I opened a new document. Then I inserted the command interface(typesetting=extended); to improve the visualization of a disequation's solution. It works in the worksheet, but it doesn't work in the content of a MathContainer.



The plot command outputs a graph of symbols where the line is made up of "H"s, vertical lines on the axes are "+"s, horizontal lines on the axes are "-"s, and intercepts are "*"s.


How do I fix this problem so that the graph displays a graph normally?

I'm writing an algorithm that takes a while and I'd like to print status messages periodically. I typically use the command line interface, and this is no problem. I just do a printf whenever I need.

However, some people who will use this code prefer to use the GUI, and I've found that the GUI tends to buffer the output from printf, printing 20-30 printf statements in clumps instead of as they're called. Is there any remedy for this?

I know this has been asked a lot, but I just want to know if there is a way to ask Maple to only show like maybe the first 1000 results instead of the whole 100000+ results? That way I don't need to overload Maple.

how to customize/invert the foreground/background color scheme in Maple?


The black on white is killing my eyes and also wasting energy, white on black is much better on the eyes and conserves energy (pixel brightness), imho


thanks in advance!
