Hello, I would like to use Maple in Statistics, but I have a problem with a speed of base functions, like generation, Mean, Range and Standard deviation. Maple computes slowly than MathCad. I have 4 test functions: Test of generation speed > restart: > > Digits :=10: > > test3:=proc(N,n) > local i,a,X; > use Statistics in > X := RandomVariable(Normal(0,1)): > for i from 1 to N do > a:=Sample(X,n): > end do: > end use; > end proc: > time(test3(30000,100)); Test of Mean speed > restart: > Digits :=10;

I have four column vectors of data points; X1,Y1,X2,Y2 (n=30) where pointA is given by (X1[n],Y1[n]) and pointB by (X2[n],Y2[n]) I can plot lines using indvidual rows with n=rownumber plot([ [X1[n],Y1[n]],[X2[n],Y2[n]] ]) However, I want to animate the plot so it shows n=1, then n=2 and etc. I am aware of the "insequence" option but I don't want to have to write the 30 entries into a "display" command. Any tips

Using the formula: ((A/B)^(3/2)*(C*D*E/F*G*H)/(I/J)^(3/2)*(K*L*M/N*O*P) I have a different list of [a1,a2....a11] for each variable except A,B,I,J which are constants. I've seen examples for using a single list, but never for using multiple lists. There are 11 numbers in each list, so I should get 11 answers. Thanks for the help. Will

I am trying to read from a embedded MathContainer a simple expression. I am using the expression func:=parse(GetProperty('MathContainer0', value)); When I execute the above code I get the error, "incorrect syntax in parse: missing operator or ';' (12)". I have read over the help pages on MathContainer, GetProperty, and parse to no help. The syntax looks fine to me. The parse help page did indicate that MathML may be reponsible, but the MathML help page was no help. What is the syntax error that is occuring? The expression works fine if I use func:=parse(GetProperty('TextArea0', value));

Hi Guys I just started learning Maple and I have basic question which is annoying me. I use Maple 10 and when I execute the following statement I get the final result as the output instead of a set of numbers. for i from 6 by 2 to 15 do print(i) end do; 14 what am I doing wrong? Am I missing something here? I tried searching all over but could not find a solution. Help is very much appreciated. Thx in advance

I have a situation which is not really complicated but it would be awkward to explain it in a text post, so I have described it in the attached worksheet. It has to do with the display of matrices. If anyone has the time to take a look at the worksheet and propose a solution I would be grateful. -Thanks View 2292_Matrix Display.mw on MapleNet or Download 2292_Matrix Display.mw

I am using the output=array([]) option in dsolve which works fine if I write in each time step of interest eg output=array([0.1,0.2,0.3]). No problem for 3 values. However, I wish to input a large number of values. Can this be automated for regular time steps?

I would like to write a procedure which uses the Weierstrass M-test on uniform convergence. I wanted to use the maximize function (to recognize if the function is bounded and to get upper bound) but this function doesn't work in many simple cases. assume(x::float); assume(n::integer); maximize(2*sin(x)+cos(x));

          maximize(2 sin(x~) + cos(x~))

maximize((-1)^n);

          -infinity

Actually, I don need maximize function but just to get any upper bound. Is there a way?

here is the matrix,for example, result:=Matrix(2, 2, {(1, 1) = 4*c-4, (1, 2) = -2*c+3, (2, 1) = -2*c+3, (2, 2) = 4*c-15/4}) for what region of c, this matrix is positive definite? I typed the following in Maple, > IsDefinite(result); / 2 \ 0 <>

Hey all just a quick question. How do you make a 3d house using the 3dplot. thanks

Suppose I have 2 Matrices, say each is 3 by 3. Is there any way I can check for the equality of all corresponding elements of the matrices without resorting to a for loop or something like that?

In diagaonalizing a Hermitian matrix, the eigenvectors come out un-normalized, and as a result, when performing a similarity transformation on the original (Hamiltonian) matrix, the diagonal elements come out proportional to the true values, not the values themselves. I can't find out how to simply normalize the eigenvectors so that they can be made into the appropriate matrix (and its transpose complex-conjugate). There's got to be a simple way, but I can't seem to find it. Can someone point the way? Thanks Carl David

Hey I am trying to do on maple to make a 3d ball which bounces up and down. Any help would be greatfully apprecaited.

Hello, Is there a mathmatical formula for horn 3D plot simulation. I tried the following but no luck so far. http://en.wikipedia.org/wiki/Cylindrical_coordinates http://mathworld.wolfram.com/Cone.html How do I convet a cone formula to a Horn formula. Where I can control the shape and size of the horn using parameters. I any help would be appreciated. Regards Raj

Hello, I need to create a picture in eps format to use it in LaTex Document. I use plotsetup to create it but the output is not worked corretly. In Maple 8 it workes. plotsetup(ps,plotoutput=`plot.ps`,plotoptions=`portrait,noborder`); and then I use some plot command. I am not able to compile the maple output in LaTexPdf. I try to open it in CorelDraw and it is opened, but I am not able to work with it like I am able with Maple 8 output. Why? Is it different format of eps? Could you help me please? How could I create eps file to use in LaTeX? Thank you very much. Vladimir
