I'm trying to determine that f(x) = (a/2)*e^(-a|x|) is a pdf for which I have tried to calcuate the integral from -infinity to +infinity but I am no getting a result that converges(even the wolfram alpha widget said the integral doesn't converge). How do I correcly implement this?

I am trying to find the pdf of the inverse of a random variable X, that represents a distribution I defined. I currently have : 

with(Statistics):
T:=Distribution(PDF=(x->piecewise(0<x and x<1,1/4,3<x and x<5,3/8,0)));
X:=RandomVariable(T);
PDF(X,u);
CDF(X,u);
Y:=1/X;
T1:=RandomVariable(Y);

but this seems to be incorrect as I get a message saying T1:=RandomVariable(Y) is being passed a wrong argument. 

What is the right way to obtain the pdf of 1/X?

 

Starting with Maple 18, the Print to PDF feature caused the document page to be hard-aligned at the left margin of the page. Maple 2015 still seems to have this problem / bug.

Does anyone else have the same problem? Has a work-around been posted? Is a fix in the works after nearly 9 months?

Hi,

Is there a way to export worksheet to pdf format but not in A4 size since some lines are going beyond the page?

When I create any plot or drawing in Maple and print to pdf, the program adds a blank space underneath the plots. How can I stop this from happening?

Example: Some code I wrote, before hitting enter

The code I wrote, before plotting the figure

After hitting enter
BTW if somebody knows how to avoid getting the extra [> I'm much obliged

 

And now a screenshot from the print to pdf

See the blank space which is suddenly added?! It really destroys my lay-out for my report. I think the solution must be an easy change in the settings, but I can't figure it out.

 

Thanks in advance

 

 

I hope you be health and happy :-)

 

Please send me a pdf of Maple 17, I have many problem about Maple 17, and can't ask whole of them here!!!

 

Hi!

I want to select 'Export using shapes for greater fidelity' under option, Export. But I can't find the tab ' Export to PDF-Format'. I'm using Maple 18 on a Mac-computer. 

Can anyone help?

Thanks

Is there a way to tell Maple to export a figure to PDF with a proper bounding box, like all of its other graphics export formats?

To export a graphics produced by Maple's plot(), I right-click on the plot, select Export, and then one of the several choices of graphics formats.  All options, other than the PDF, work fine—they produce graphics files whose bounding boxes correspond to the extents of the image.  Exporting to PDF misbehaves—it produces the equivalent of a 8.5''x11'' paper and inserts the graphics somewhere near the upper left corner.  I am absolutely at a loss to see the utility of that.  What in the world is the use of such an export?

Is there a configuration setting that tells Maple to save to PDF with a proper bounding box?  I looked around but couldn't find one.

Hi

What can i do to prevemt maple from resizing my drawings and inserting empty space beneath drawings?

It happens when i export to pdf or print the document out.

Is there any other way i can export to a readable format without this happening?

It seems a frequent issue that exported 3d plots are not shown as wished. I experience the same problem. Although I exported in the .eps format into a .tex latex-file the resulting .pdf-file shows a somewhat pixelated image of my 3d plot as if it was created in "Paint". Is there a solution for this in Maple13?

Hello people in Mapleprimes,

 

I want to do calculations about an expected value.

For example,

expectedvalueofc.pdf

that is, \int_a^b c d \Omega

 

where, \Omega is a distribution function of c. 

 

But, I don't know whether this equation can be put into worksheet.

Is there no way other than writing this as 

\int_a^b c g(c) dc, 

where g shows a probability density function.

 

Can I use Statistics[ExpectedValue] to calculate expected value with a general distribution function, not specified 

to normal distribution?

 

I hope you will give me some hints.

 

Best wishes.

 

 

 

According to kernelopts(version), I am using Maple 16.02, X86 64 LINUX, Nov 18 2012, Build ID 7888210 , having just updated

Maple 16.

I have a Maple worksheet with some graphs of 10^5 data points. When I export the worksheet to a pdf for inclusion in a LaTeX document (with pdfpages package, this recognizes page breaks), the file is around 100 Mb, much larger than I would like.

It seems that the file is large as a figure in the pdf is not just an image, the pdf seems to contain all of the information necessary to plot each data point individually.

Is there some way to encourage Maple 16 to treat figures as bitmaps (or something similarly much smaller than the original figures) upon exporting a worksheet to a pdf? I'll be happy for any suggestions.

NOTES:

1. This question was originally for Maple 16.00. Updating to 16.02a has not solved the problem.

2. I am suspicious that there is some bug in how Maple 16 exports figures made with "plot" to a pdf file.

When I try various methods of compressing the pdf that I've seen on the web, such as with pdftk 1.44, or ghostscript 8.70 or 9.07,  or pdf2ps followed by ps2pdf ,

error messages are returned. For example using pdftk:

pdftk input.pdf output.pdf

gives

"Done. Input errors, so no output created"

 

When greek symbols are used in code edit region (by copying from worksheet 2d math mode), they used to get exported properly to PDF but the only issue was large code edit region used to get cut off. But now with this new 18.01 update, code edit region is not cut off but greek symbol inside code edit region are not appearing in PDF export instead just pink boxes. Has anyone else also encountered this issue and suggest a resolution.

Hi, i am trying to export the following bifurcation diagram into a pdf.

 

Digits:=20: N:=10000: M:=100: x_max:=1: r_min:=0:
r_max:=4: for n from 0 to N do r:=r_min+n/N*(r_max-r_min):
x:=evalf(x_max*rand()/10^12):for m from 0 to M do x:=x*exp(r*(1 - x)): od:
X[n]:=x: od:
with(plots):
bifpoint:={seq([r_min+j/N*(r_max-r_min),X[j]],j=0..N)}:
pitchf:=pointplot(bifpoint,symbol=point):display(pitchf);

 

For some reason the graph is just blank, with just the axis when i export to pdf.
