### Autoplay plot animations?...

18 hours ago

Hi, is it possible to instantly start the display of plot animations after they are generated in maple? I searched for answers in the documentation and on the internet but couldn't find a solution. I would like to skip the step of manually clicking the plot and the "play animation" button.

### output display in matlab...

I have been puzzled by a matlab toolbox problem for a long time. How can I get Maple notation in matlab output?

Both "Input display" and "Output display" in Tools-->Options-->Display was changed from "2-D Math notation" into "Maple notation". And the output in Maple is indeed Maple notation like this:

But the output in matlab is also 2-D notation like this:

when copy it to Matlab or Maple as input, it become the wrong issues like this:

How can I output Maple notation in matlab? The version is Maple 18 and Matlab 2014b, respectively.

### Can I use plots[display] with plots[polygonplot3d]...

April 10 2015

Hi,

I want to display several plots insequence and tried creating a list of polygonplot3d objects called "plotlist" and using them as an argument like this:

display(plotlist)

which triggered the error message:

Error, (in plots:-display) expecting plot structure but received: plotlist

Where's my mistake and how could I achieve the desired outcome? (displaying polygon3dplots in sequence)

Best Regards

### How to build a color legend based on angle....

April 10 2015
3 0

I have generated a picture using pointplot and display that creates a grid of colors based on the angle between vectors and (1,0) in R^2. Each angle is given a unique color via the HSV color space. I would like to provide a legend explaining the colour, something along the lines of

red (brown) green (blue) red
0                Pi                 2*Pi

and possibly

red       (brown)       green
angle1                     angle2

Is there an easy way to do this, or will I have to mess around with a custom pointplot/textplot solution?

### How can I access data in a matrix that's too big t...

March 22 2015

Hello!

I performed a calculation where the output was a matrix that Maple said was too big to display explicitly. So, this output was just a summary. Specifically, something like this:

How can I save/export the data inside it to another matrix so that I can manipulate it while staying within Maple?

I can export to an external file using

and then reimport the data back into Maple. But this is cumbersome.

I can also see the data on my screen by double-clicking on the matrix. But I haven't been able to manage to copy & paste it within Maple or transfer it to another matrix so I can manipulate the data. How do I do this? I'd like to stay within Maple to avoid the hassle of exporting data to Excel & then reimporting it.

Thanks,

Damian.

### revised mathematical visualization...

Hello,

I need help writing a maple code to calculate the normal to the curve X^2-2X at x=1.5

and also display the curve, the tangent, and the normal on the same plot in the range x=[-10,10].

I manage to answer the question, but i am not quite certain if i have written a proper code..please if someone can review my solution and advise me i would really appreciate it....

I also would like to also make visisble the point of tangency at x=1.5 and give description of the figure but i am not sure how to do so...

how can i cut and paste the exact code with the images....it seesm that it doesnt allow me to do direct cut and paste so i changed it to 1-D and paste it into this page..

restart;

f := proc (x) options operator, arrow; x^2-2*x end proc;

(D(f))(x);

#Then, the slope of the line tangent to the graph of f(x) at the point with x-coordinate, x=1.5 is,

D(f)*at*x = 1.5;

evalf((D(f))(1.5));

#The y-coordinate of the point is

f(x)*at*x = 1.5;

evalf(f(1.5));

showtangent(f(x), x = 1.5, color = [black, purple]);

plot([f(x), (D(f))(1.5)*(x-1.5)+f(1.5)], x = -10 .. 10, y = -10 .. 10, color = [black, purple]);

plot([x^2-2*x, x-1.5-.75, -x+.75], x = -10 .. 10, y = -10 .. 10, color = [black, purple, pink]);

Hi

I need to display amounts of M2 and 1.15*P2 instead of Notations

TEXT([M2,1.15*P2],'(M2,1.15P2)

### why print(proc) does not show the same code as sho...

There is a slight display difference of the code between showstate() and print(). It has to do with ' name ' use where print does not show the outside '' characters.

Here is an example

restart;
showstat(dsolve);

and now using print

restart;
interface(verboseproc=3);
print(dsolve);

When I used

with(LibraryTools);
Browse();

and looked at the source code there, it matched what showstat(dsolve); gave and not the print command. Is there a reason why print does not show all those extra characters exactly as in the source code? It seems a formatting issue, but it is better to be looking at an exact copy of the source code.

### how to change matrix brackets from [] to () ?...

When I export to latex a matrix  <<a|b>,<c|d>>, the latex uses \begin[ and \end]

\left[ \begin {array}{cc} a&b\\ \noalign{\medskip}c&d\end {array} \right]
Is there a way to make Maple use () parenthesis instead of []? The screen display is not important for me in Maple, but I'd the latex to use () instead.  It will be nice if there is way to configure this. I looked but could not find an option.

### maple 2015 no longer auto-scroll as computation is...

March 04 2015

I run the same notebook in Maple 2015 that I used to run in Maple 18.02.

I noticed that it no longer auto-scroll when the print messages reached the bottom of the window as it did with Maple 18.02. This means, I can't see which line the computation is at at the moment, since I can't see the last line printed (it is not visible), without me having to manually use the vertical slider to scroll down trying to catch up with it. But it is hard to do this all the time.  It starts to scroll ok until the last printed message reached the bottom of the window, but then it stops.

This is very annoying, becuase I'd like to see the messages as it is running, so I know which equation is being solved when I look at the screen.  The messages are like this, with some print message I put in the loop

memory used=0.53MiB, alloc change=0 bytes, cpu time=16.00ms, real time=7.00ms, gc time=0ns
*** loop counter 100
etc..

Is there an option one has to configure to make the screen scoll with the output? I looked but do not see one now.

I do not remember having to do anything in Maple 18.02. It seems natural that it should scroll down as messages are being displayed. This is how all apps work.

I am using Maple 2015, windows 7, 64 bit OS and 64 bit Maple. Using Worksheet, was created in Maple 18.02. Other than this, everything else works ok so far.

### Animating combined 3d plots...

Hi everyone,

I am using the following code (by dr. Corless) to animate a Riemann surface:

restart;
with(plots);
B := 1.5;
u2 := r*cos(th); v2 := r*sin(th);
w1 := u1+I*v1; w2 := u2+I*v2;
z1 := evalc(w1^2); z2 := evalc(w2^2);
x1 := evalc(Re(z1)); x2 := evalc(Re(z2));
y1 := evalc(Im(z1)); y2 := evalc(Im(z2));
f1 := proc (theta) options operator, arrow; plot3d([-x1, -y1, v1], u1 = -6 .. 1, v1 = -B .. B, grid = [50, 50], orientation = [theta, 80], color = u1) end proc;
f2 := proc (theta) options operator, arrow; plot3d([-x2, -y2, v2], r = 1 .. 1, th = -Pi .. Pi, grid = [50, 50], orientation = [theta, 80], color = black) end proc;
display(seq([f1(10*k), f2(10*k)], k = -17 .. 18), insequence = true, axes = box, view = [-1 .. 1, -1 .. 1, -B .. B]);

f1 is the Riemann surface and f2 is the winding curve.

The animation works fine on the individual plots, i.e. when I do:

display(seq(f1(10*k), k = -17 .. 18), insequence = true, axes = box, view = [-1 .. 1, -1 .. 1, -B .. B]);

or

display(seq(f2(10*k), k = -17 .. 18), insequence = true, axes = box, view = [-1 .. 1, -1 .. 1, -B .. B]);

but with both f's (as in my modification)  the animation does not combine correctly the two plots and shows them separately. Is there any way I can combine the plots so that display produces a smooth animation with each rotated frame containing its winding curve?

Many thanks,

Yiannis
