Hello everyone

It seems I can't live without keyboard shortcuts :-) Is there is a short cut for the following commands:

execute the entire worksheet
remove output from sheet
join/split execution groups

I'm on mac.

thanks.

hi

i have the following function

f[1](x):=_C2 (e)^x-_C1 (e)^(-x)+1/2 x (e)^(-x) h1+1/2 (e)^(-x) h1+_C3

with thease boundary conditions:   f[1](x))=0,diff(f[1](x),x))=1,diff(f[1](x),x),x=infinity)

i want to find cinstants C1,C2,C3 where h1 is arbitrary parametr.

i write the following code but its doesnt work correctly

s1:=simplify(subs(x=0,f[1](x))=0);
s2:=simplify(subs(x=0,diff(f[1](x),x))=1);

I am calculating the dotproduct in maple 15 of two very large vectors. Are there any tricks/ways to speed up such a calculation? Maple is taking a very long time to execute the calculation and I am unsure whether it will actually return a result.

I'm using maple code of the form DotProduct(vector1,vector2);

Any advice ?

On the usenet newsgroup sci.math.symbolic Prof. Richard Fateman posted a question (or here) recently about what mechanisms a math application could use to handle the situation of negligible imaginary parts of computed data when plotting.

An example could...

Good Morning.

I would like to know where Maple is statistics compared with other software. As a justification for the thesis i am doing. I found a page http://www.scientificweb.com/ncrunch/, but a report in 2008. I wish something more recent.

Thanks

I understand that porting Maple to Android would be a pretty big job, but does anyone know of any plans to at least make an Android program capable of viewing Maple worksheets?  It would be really handy to be able to show my work to someone using an Android tablet, which is certainly capable of rendering graphs and such.

I performed the following procedure to simulate the function of Matlab soundsc(Scale data and play as sound).



N := 16000;
 t := Vector(N, i-> evalf(2*i/(N-1)) end proc);

sound1 := sin~((2*evalf(Pi)*440)*t);

aud := Create(sound1, duration = 10.0);

PlayWave := proc (data, SampleFreq)
local SoundFile;
setattribute(data, SampleFreq, 16, 1);
SoundFile := "Bflat3.wav";
Write(SoundFile, data);
process[launch](cat("sndrec32.exe ", SoundFile))

I have a matrix containing numeric values of functions. Each column corresponds to a function. The first element of each column is a name of a function and following elements are numeric values of this function.

For example:

t      a         b     c         d
0    0.5      38    0       0.9e-5

Question:

Let say you have a revolver with six chambers. There are two bullets in the gun. The bullets are
located in two chambers next to each other. You now want to play Russian roulette. You spin
the barrel so that you don’t know where the bullets are and then pull the trigger. We assume
that you don’t kill yourself with this first attempt. Now assuming that you want to maximize
the chance of not killing yourself is it...

How to update a file extension m to extension mla ?
I will need to update the hdb file accompanying ?
Achievement in maple download the file with extension m, but does not display help.

Hello together,

thanks for helping me with my earlier problem. I now managed to put toether a plot which suits my purposes, but i can't manage to Export it using the e.g. plotsetup(gif, plotoutput = "C:\\Test.gif") command.

I don't get an output but a warning: Warning, ignoring axis information in _AXIS[n] structures

If i switch back to plotsetup(default) everything is displayed in the editor window.

Anybody any ideas? If...

Hi 

I have a area described by two functions x(eta,xi) and y(eta,xi) describing the x and y coordinate, respectively. I would like to plot this area for eta = -1..1, xi=-1..1. I have tried with plot([x, y], eta = -1 .. 1, xi = -1 .. 1, axes = boxed) but is does not work. How can i do this?

Thanks in advance.

hi, i am a danish htx student and we use maple for our math lessons, when i started here i installed maple 13 and it has been working fine, but our serial runs out so i had to upgrade to maple 15. when i did i uninstalled the previous maple version and installed the 64 bit maple for my 64 bit windows vista. now when i try to do for instance f(x), the ( and ) breaks maple and all text/numbers vanishes, if i open my previous school homework they look empty aswell. clicking and...

Hello togehter,

i switched for various reasons from Gnuplot to Maple for plotting my data.

1) Is there a way to label the secondary x (top) and secondary y axis (right) in boxed axis style. Attached you find a picture from a Gnuplot i've done and the plot i'm currently working on in maple.

2) I do like the black "cross" in the midlle refering to the x,y axis at zero positions. Is there a way to do this, as well.

Gnuplot:
