Tablet Handwriting App that works well with Maple?

Dakota — Thu, 05 Apr 2012 20:06:50 Z

I have an older tablet PC on which I recently used Windows Journal for handwriting and storing my lecture notes (on the swivel screen with a stylus). However, Windows Journal is very basic (doesn't interact with Maple or anything else other than pasting images into it) and has very limited drawing capabilities (rectangles, ellipses, and only horizontal lines).

What tablet PC apps do you recommend for handwriting, drawing, etc. that interact well with Maple

key bindings and acceptance of automatic key presses

itsme — Mon, 19 Mar 2012 22:34:56 Z

Hi Everyone:

As far as I know maple has no way to define key bindings for it's actions.

I would however like to be able to navigate around the worksheet using hjkl keys - namely alt+j would be equivalent to down_arrow, and so on. I find that I spend more time reaching for the arrow keys or the mouse than writing useful code (I might be exaggerating slightly here ;) ). I can implement this behavior easily using my window manager (FVWM) - meaning the window...

context of print/rtable

icegood — Tue, 28 Feb 2012 00:57:39 Z

In which context runs subj? Why all time when i start debugging with 'stoperror' it stops at 'interface' call i.e. in debugger

interface('prettyprint')

doesn't return 3 as worksheet returns. It return interface('prettyprint') i.e. symbol.

Startupcode question

Ratch — Mon, 19 Sep 2011 01:13:48 Z

I am trying to see what is in the startupcode file by using the Edit->Startup Code. I know that somewhere is a command called interface(imaginaryunit=j) because it works when I restart. I cannot even change anything because it does not show anything in the editor and nothing takes effect.

suppress warnings using writeto

hubertbauer — Tue, 07 Jun 2011 09:42:49 Z

I've got the problem of warnings polluting my text outputs.

If I use interface(warnlevel = 0) the warnings are suppressed in the terminal but not in the files exported by the writeto command.

A sample:

> restart;with(CodeGeneration); with(plots); with(ListTools); with(FileTools);
> Matlab(u(1) = 3);
Warning, the function names {u} are not recognized in the target language
cg = u(1) == 3;
> interface(warnlevel = 0); Matlab(u(1) = 3);

Problems with my interface(displayprecision=3)

jean-jacques — Thu, 27 Jan 2011 22:43:14 Z

Hello,

It is obvious why my command

interface(precision=3)

is not working?. I get 10 decimals(commands below and output in attached file).

I hope it is easy to fix.

Kindest regardsSSSzzzz

restart:
f1 := (w1, w2,n) -> add(add(
`if` (1/2 <= w1+j*w2+((1/n)*(1-w1-w2))*k and
j*w2 +((1/n)*(1-w1-w2))*k < 1/2 ,

keyboard shortcuts / customization

itsme — Sun, 23 Jan 2011 21:00:11 Z

What is the equivalent of

Shift+Tab = move the cursor to the previous region

on linux?? it is listed as working on windowns/macs but not on linux.

Also is there a way to customize keyboard shortucts? I am a vim user and navigating around a document in maple's gui is really painful (by the way I work in the "worksheet" mode)

thank you.

Observations of a returning student...Maple 14

Ninetrees — Wed, 01 Dec 2010 17:12:51 Z

Maple 14 - returning after not using Maple since M13...

1. Still can't figure out how to scale images and text. I tried putting an image in a table cell with some text next to it. The only way I can see is to put any images in a space by themselves and not relate them to text. What I see on the screen has little relevance to the printed product, and the only way I have found to scale images correctly is by trial and error. See #6 below for time penalty for changing a table cell size.

2. I don't get to choose the header/footer font size?

3. The footer date format is 12/1/10, which is very nearly the worst it could be, and doesn't respect my Windows settings: 2010.12.01.

4. There is no option to use the file save date rather than the current date.

5. Dragging a corner of an image changes the scaling. IMO, that's what the tabs on the sides and top/bottom are for. Dragging corners should preserve scaling.

6. Changing a cell size in a table means waiting 10 s to get full access to Maple menus and the document (dual 3.4 GHz CPU, 3 GB RAM).

7. I clicked on the Space Shuttle Sim to get an idea of what Maple can do, and then waited 10-15s while Maple played with the palettes and swapped to a new document.

I guess that Maple is about more than this, but I am [relatively] new to it, so I begin where I can...these are usability issues. I understand that Maple has been selling the doc interface for a few releases, but not made much progress.

I guess that I can kiss (no, I'm not upset, just a style of speech) off the document mode and just use the power of Maple to calculate what I need and copy the results in to a word processing program...

[a few hours later] I should say that I found some more comments on the slow interface, and took the hints to close the palettes, which sped things up quite a bit...the penalty is, of course, that I must open them to use them, and that sort of defeats the purpose. Still, if I regard them as drop menus...

There is still the issue of scaling images, and I guess from a quick glance at the included examples that Maple has not figured out how to handle images. I tried to lock the image size, but have not found a way to do so. The quick tutorial on the Maple web site was a great help in getting up to speed quickly.

Suppress or show output in Maple

Jeff — Sat, 27 Nov 2010 21:39:07 Z

Hi. I'm new to Maple. I like the idea, but am rally confused by the interface. Can someone answer a few questions please?

How come this works, but displays wrong (the quotes display):

printf("%5a %12a %12a %12a %12a %12a %12a\\n", "-", "--", "--", "--", "--", "--", "--");

But this doesn't work (replaced quotes with apostrophe):

printf("%5a %12a...

The magic of java

John Peterson — Thu, 16 Sep 2010 23:34:58 Z

An example of the magic of java. It has an excellent widget toolkit too! Study the beautiful image below for an example of what it can accomplish.

When selecting Plot > Plot Builder > Options the gui hanged like this with no way to restore the program, the x buttons had no effect, and no other input had an effect. I was left to close the process and lose my changes to the .mw file. It's running on XP 64-bit.

How can I view 'sub-portions' of Maple procedures?

RossC — Wed, 18 Aug 2010 15:42:45 Z

I am trying to learn more about certain maple functions using:

interface(verboseproc=2):
readlib(fsolve); #for example

This works well, but sometimes the function calls something else that I don't quite understand. An example for fsolve is when it has decided to use Newton's method:

#this is taken somewhere from inside the fsolve procedure

sol:='fsolve/sysnewton'(eqs,[r])

I can't figure out how to view the code for this...

Java Interface Problem

bvmartin7604 — Mon, 02 Aug 2010 21:41:17 Z

Hi,

I just purchased the personal edition of Maple 14. It was working just fine for 3 or 4 days but now the java interface is distored. Even hovering the mouse over the palettes or images causes distortions. I've uninstalled and reinstalled several times but it hasn't worked.

Has anybody else encountered this? Does anybody have a solution?
