Hello, Please how do I compute cdf of student t distribution in maple Tξ+1(.). I have a function that i nvolves student t distribution but finding it difficult to compute student t in the funcion. I am new to maple.

Hi all,

I tried to create the*.exe file by C and call the kernel of maple for calculation.

To understand the OpenMaple, I ran the OpenMaple C code sample, “simple.c” in “<Maple>\ samples\OpenMaple\simple” through Microsoft Visual C++ 2008 but got the incorrect result:

It’s seems that the error is happen due to the wrong maple directory. But according to the description of "kernelopts" in help, the value of mapledir cannot be set.

Refer to the description of  "OpenMaple,Examples" in help , both header file path and library file path had been set:

O/S: Windows (32-bit)

Header file Directories: "C:\Program Files\Maple 17\extern\include"

Library Directories: "C:\Program Files\Maple 17\bin.win"

Environment Variable: "C:\program files\Maple 17\bin.win"

I'd appreciate any help on this topic. Thank a lot.

Dear Maple experts:

I have a very simple question:

I have a polynomial p(x) with integer coefficients and a prime p.  I want to reduce the exponents of this polynomial mod p.  So for example, if p(x) = 1 + x^3 + x^17 + x^19 and p is 17. Then I want Maple to output 1+x^3+1+x^2.

I know how to reduce the coefficients mod p, but not the exponents. Can someone suggest how I might go about doing this.  Thank you very much for your help.

Best wishes

Sunil

if ((a.d-b.c)=0) then print([0,0,0,0])
fi;
MARK:=(a,b,c,d)->[d/(a.d-b.c),-b/(a.d-b.c),-c/(a.d-b.c),a/(a.d-b.c)];

How can I get solution of  the following equation of orbit for schwarzschild BH in form of Jacobi Elliptical Integrals on Maple 12 platform,

diff(r(phi), phi) = r^2*sqrt(e^2-(1-2*M/r)*(1+l^2/r^2))/l

I'm simplifying this Reynolds Equation starting from here:

Reynolds:=Diff(p(x)*h(x)^3/(12*mu)*Diff(p(x),x),x)-u(x)/2*Diff(p(x)*h(x),x)+Diff(p(x)*h(x)^3/(12*mu)*Diff(p(x),z),z)=Diff(p(x)*h(x),t):

Then I apply the dchange command:

dchange({p(x)=P(X)*Pa,x=Lx*X,h(x)=H(X)*h2},Reynolds,{P,h,X,u,H});

The problem is that it expands the new derivatives and I need the equation in its compact form.

How do I tel Maple only to make the substitution but not to expand the result?

I know that it expands by default, can I modify that?

Hi I have been trying to get the inperpolation of some values within a procedure without much success. Maybe someone in mapleprimes might know this already.

Basically what I am trying to do is to generate a matrix of values. The values of the columns 1 to 3 are just some values, but then I want column 4 to be the result of the interpolation of some values.

I got different errors such as: 

Error, (in CurveFitting:-ArrayInterpolation) data must consist of real, floating point values

Anyway the procedure is shown below:

InterProc := proc ()

local i; global A, global variable1, global variable2;

A := Matrix(1 .. 4);

variable1 := [0, 100];

variable2 := [12, 20];

with(CurveFitting);

for i from 1 to 10 do

 A(i, 1) := 3+i;

 A(i, 2) := 2*i+A(i, 1);

 A(i, 3) := A(i, 2)-1;

 A(i, 4) := ArrayInterpolation(variable1, variable2, A(i, 1));

end do;

end proc;

InterProc();

M:= Matrix ([[a,b], [c,d]])

If a.d-b.c=0 then print (Matrix(2)); else print (Matrix ([[(d/a.d-b.c), (-b/a.d-b.c)], [-c/a.d-b.c, a/a.d-b.c]]); end if;

I don't understand where I have gone wrong. If anybody could help I would be greatly appreciative

Thank you

Has anyone used Maple for Empirical Mode Decomposition ? Any tips, Maple docs ? I can't seem to find anything when searching Maple sites.

I have recently written a maple program to deconvolute gamma-ray spectra using the Richardson-Lucy algrithm. Although this method works well I would prefer to use a method based on the Maximum Entropy algorithm, and would like to know if anyone has tried to write a Maple program to deconvolute 1 dimensional data?

Hi.

I'm having a problem with this little guy "cos(Phi1(x)-psi)". When printed, it becomes "cos(-Phi1(x)+psi)", when Maple does not know what Phi1(x) or psi are. No matter what sign i set for psi, it will only display +psi when printed. Anyone know what causes this?

In ode solve command i generated a large array data. The output shows a large order matrix of this form

[110001x6 Matrix

Datatype:Anything

Storage:rectangular

order:Fortran_order].

I want to export this matrix into a notepad. Which can then be used for plotting in TecPlot. 

Looking for good response

I downloaded Maple 17 student eddition for linux and when I click on the bin file to install it I get an error that says "This file is of unknown type". It gives the option to find an aplication local or online and it says no aplications available or the "MIME" file type canot be installed on this system. Im not sure what to do, do I need somthing to unpack the file or is it just not aplicable on my linux operating system (version: Cinnamon version 1.8.8 LinuxMint: olivia(X86-64))?

In physics as in math, we often use delta to indicate a (small but finite) variation in a parameter (e.g. delta x). Sometimes Delta (capital delta) is used for a larger variation, and there are even constructs like delta Delta x (a small variation of a larger variation in x). (Don't laugh or frown, this is being done & makes sense in certain situations.)

How do I write this best in Maple, esp. when I use 2-d math and am working on a (live-) script that may be handed out to others incl. students,? I.e. the appearance matters. Just writing delta x is interpreted (in 2-d input) as delta*x which is not what is meant (and leads to funny effects after the first simplify). If I write deltax (one word) then delta does not typeset in its proper greek form, which becomes an issue if you have many of these. I can write delta(x) and that often works (as long as you don't try to differentiate by x), but the typeset equation does not look right either (delta is not a function of x).

Is there a god way of doing this, or am I hitting a wall here?

TIA,

question 2 of my homework is actually abit more simple imo. i think i performed all the operations correctly but however my 3dplot shows just a flat plane. i dont think thats right. if someone could take a look at my code in reference to this question. it would be great.

Suppose that a baseball is hit from 5 feet off of the ground with an initial velocity of 40 feet per second at an angle of above the horizontal. Let the horizontal and vertical components of the position, velocity, and acceleration be denoted respectively by and . Assume that the only acceleration is due to gravity (i.e, ).

a) If , plot the parametric equations over the time period that the ball is in the air.

b) Clear in maple by typing theta:='theta'; Now, suppose that we write in Cartesian form by solving for t: t:=solve(rx=x,t); Typing in ry should now yield a function that involves only x and . Make a 3-dimensional plot of for ,
