Hi everyone,

I want to create a Gaussian PDF so I need to calculate Determinant(sigma) with sigma the covariance matrix of a gaussian variable.

If we call this variable alpha (which is a 12 dimension vector and represents the noise in a discrete dynamical equation), then sigma_ij=ExpectedValue(alpha_i*alpha_j)-ExpectedValue(alpha_i)*ExpectedValue(alpha_j)

and this is zero most of the time! So the covariance matrix is singular and the determinant is zero. 

Want create my own geometric distribution with rather only natural values i.e. without zero:

c:=Distribution(PDF=(t->PDF(Geometric(p),t-1)));
But such form is luck to calculate even Mean value:

simplify(Mean(c)) fails. How to apply to get even Mean(F(c)) for complicated enough F?

Hello,

I have four old Maple 10 Worksheets sitting around my harddrive. I'd like to view them again, but my Maple 10 license won't be activated again, they tell me to buy a new 13 or 14 one.

Does anyone still have a Maple 10 (or compatible) version and would convert four small worksheets into PDF for me?

Thanks!

HI,

I have been trying to convert a small script (Maple 15) to latex but ran into a strange problem. Literal subscripts don't seem to work.

When I have, for example " f_a " latex will generate a pdf, as expected, with " f_a ". However, if I have " f(ctrl+shift+_)a " I get "  ‘#msub(mi("f"),mi("a"))‘ ".

I am kind of new to this maple+latex thing and have searched everywhere for a solution but without...

restart; with(Statistics)

#Define:

A := RandomVariable(Geometric(p))+1; F := Mean(A);M := abs(A-F)/A;

#and ask Maple to find a pdf of the r.v. M:

f := `assuming`([PDF(M, x)], [x > 0])

#Maple 15 gives an answer, but what does it mean by the output for this input

subs(p = 1/3, x = 3, f)

#or how do I plot this pdf of M? Does Maple give a correct answer?

# Why does the error message appear when I do subs(p = 1/3, x < 3, f...

I'm looking for information on the x3d format, with a view to converting x3d to 3d-pdf.

1. x3d formats are available from standard gui by right-clicking to "export".  How can you use plotsetup to access the "Extensible 3D" format with a line of code?
2. what x3d viewer do you recommend?
3. do you have any tips on converting x3d to pdf?

Let me elaborate to provide context to my questions. In a previous post (

Dear All

Suppose that you have a pdf for the number of request receiving to a system with mean m. Suppose that it is not a common distribution.

Is it correct that there is a time between request with a specific distribution and the mean value of distribution is 1/m.

Is there any math rule that can prove it?

Best Regards,

Dear All,

Hi. I am interested to find the pdf of this moment function: phi(t) = exp(a * b / p (e^(a*t) -1))

This is a moment of random variable Y = aX where X is a Poisson random variable with rate (a*b/p)

I want to know is it possible to find a pdf from its moment in maple?

If so how?

Best Regards,

Saeid

Hi All

If we have extensive material in pdf format and we want to tranfer this information to Maple and use it it as the main editor and word proceesor on a go forward basis - Is it possible to copy a pdf document with extensive equations into Maple while maintaining the format particularly of the equations, pictures, drawings and plots? Any copying and pasting I do now garlbles up the equations, plots and pictures of the pages I import to Maple...

Im currently doing number 1 right now on this lab which i attached, and i cant seem to think of a function that suites that description, im going to ask my instructor for more clarification, but i was wondering if anyone could give me some suggestions on how i could come up with the one needed

Thanks!

Hi, im having some trouble with Math182_Lab_4_2007W.pdf with question 7, its giving me hints on how to set up my X and Y from the old points of x1 and y1, but my instructor forgot to teach us using the map command and im having trouble on what to do next.

i'll include my worksheet, MAT_182_-_Lab_#_4.mw

I have a document that prints a square over one of the letters in a string when I export as PDF. This does not happen when I print to CutePDF...I suspect some sort of "hidden" character in the file, but don't know how to access it...

sorry for this funny question, but where is the "Print Preview" command, it is not under File menu anymore and the export to PDF function is also missing... What am I doing wrong?

running Maple 14 under Max OS X, SL.

cheers.

Hi everybody,

I am using Maple 14 in document mode. Recently I encountered the problem with exporting polish special characters (like ąęćłóńśźż) into PDF file. Maple 14 just omits them. Why?

As sometimes the question comes up "how to have a pdf documents for this?" here is a free way to such on Windows:

PDFCreator

Essentially by that you install a printer, which just does it. And as such allows to print threads here from the board, or Maple sheets or simply from any application.

After some configuration hanky-panky it is easy to use.
