Maple Professionals: I wish to import a file with float type values which is 338*16 big. I saved it in Excel as a .csv type file. Using the Import Assistant works. However I don´t want to use the assisstant everya time I run my calculations. Thus I tried to use the commands readdata(), ImportMatrix(). Hoever non of those do like me :-(. I am really frustrated. I attempted the following commands, having already converted the csv into a txt: > lambda:=ImportMatrix("D:\01_1_CSML DATA\Prognose & Bestände\04_2.txt",datatype=anything); Error, (in ImportMatrix) file or directory does not exist

In reading through the Maple 11 "Getting Started Guide," on page 81 is paragraph 4.2, which is titled "Top Commands," the booklet lists and describes a number of commands such as plot, solve, fsolve, eval, etc., with out any comment. What is the significance of these commands among the many, and what is meant by "top" commands. Is there a hierarchy of commands? Or do they mean these are the most used or what? I don't understand what I am missing here or why this list of commands in included. Again, there is no discussion, just the table of commands.

Hello, I have a do-loop printing "n" occurences of a certain calculation+plot. Each one has a different length. It would be neater to skip to the top of new page each time. How do I give the instruction: "move to the top of the next blank page"? Thanks. Philippe Baille

Hello everybody. This is my first post. I'm currently using Maple 10 for a project in my school and i need to create types. I'm improving an "automatism library" called AutoSLI and for example i have to create a "transfert function" type. I want to use the type in functions like that : "zeros(Transfertfunction :: f) I use a "Record" structure inside a function. I make some tests to see if the parameters entered are correct then i create the object but it don't works when i use 'type/transfertFunction'. It creates the object when i take back the name of the type. Maybe the choice to put the creation in a function is not good.

I have a regression problem for which I need to neglect a certain corner of parameter space because the function I am trying to fit for becomes imaginary in this region. I have everything written so that I may use NonlinearFitMatrixForm, which works really well when I hold one of the problematic parameters fixed and set the limits of the other to within the real region of parameter space. However, to extend this problem to fit for all parameters I need to tell the procedure to only look in the section of parameter space where some complicated function of two of the parameters is positive. Thanks in advance for any help,

Hello, I'm trying to calculate the following definite integral: int(ln(1-8*Pi^2*ns*e^2*N/(m*(omega^2-e^2*B^2/m^2)*L*sin(t)*kappa*((kappa*tanh(2*Pi*N*d1/(L*sin(t)))+1)/(kappa+tanh(2*Pi*N*d1/(L*sin(t))))+(kappa*tanh(2*Pi*N*d2/(L*sin(t)))+1)/(kappa+tanh(2*Pi*N*d2/(L*sin(t))))))),t=0..Pi/2); Maple10 tries to solve it for ~20 minutes and then gives up, returning the same expression. Do I have to explicitly set singularities? Thanks in advance, Pedro

I would like to calculate int( 1/Pi*s^s*(1-s)^(1-s)*sin(Pi*s),s=0..1), but I don't know how do this by Maple. Thanks, Sandor

Hi, I am adminisering an installation of MapleTA 2.5. I would like to change the maxsize of upload course modules from 1MB to ex. 2MB.Please tell me where to do so.. Best regards Gert Espersen University of Aalborg Denmark

hi everyone i wanted to know if maple 11 can show the steps in which the solution was reached? for example to find the antiderivative of f(x) = e^(4*x)+e^(-4*x) is there anyway to make Maple 11 to actually show the steps taken to reach the solution instead of just seeing the solution. it'll help me a lot better with understanding things and finding my way around some problems. thanx in advance

I'm new to Maple, and I was hoping someone could help me! I have a formula for a hyperbola, 9x^2-y^2-72x+8y+119=0, and it states to find the standard form. The standard form is supposed to be two fractions that are set equal to 1. I have Maple 10, and the only thing I've been able to find so far has been to select "apply a command" from the context menu and type in "completesquare", but either I'm missing a step, or I'm doing something incorrectly. Any help would be greatly appreciated!! Thanks!

Below is a link to something I did today with Maple. I'm relatively new to Maple and am only familar with a handful of it's built-in functions, so a lot of what is shown in the worksheet could probably be done a lot easier - for example I think Jacques, as an answer to a question of mine here, was suggesting that using Maple tables might be a better way of doing what I did here with arrays. Anyhow, I had a lot of fun doing it the way I did, and I thought maybe someone here might find something in it useful, or may just like to have a look at what a "newbie" such as myself might be doing with Maple.

Hello, everybody,

I am trying to put on the same graph several sets of inequalities and to color them differently (that is, to have several areas in different colors).
I am using inequal (see below), and the color of optionsexcluded of the first set of inequalities colors all the rest. I tried to make it transparent but could not (white does not work).

area1 := inequal({x>=0,y>=0,x+y<=0.5},x=0..1,y=0..1):
area2 := inequal({x<=1,y<=1,x+y>=1.5},x=0..1,y=0..1):
display([area1,area2]);

Hi I am having a problem with the output of my proc file. I wrote a proc as follows: Energy:=proc(n) local x,y,..; . . . . . plots[listdensityplot](H, labels=[Energy, Magnetisation]); W:=T->add(add(N[a,b]*b^2*exp(-a/(k*T)),a=Emin..Emax),b=Mmin..Mmax)/add(add(N[a,b]*exp(-a/(k*T)), a=Emin..Emax), b=Mmin..Mmax) plot(W(T)/n^4,T=0..5, labels=[Temperature, "

Hi everyone, I am trying to understand how to use Maple to generate a C code. I started with the help and I read it several times but still I think I didn't get it all. The function I am working with is, with(CodeGeneration); A = proc (k) local mysum; declare = [mysum::numeric, k::integer]; for k from 1 by 1 to 10 do mysum := 1+2*k end do; end proc: C(A) But the result I am getting is [C, Fortran, IntermediateCode, Java, LanguageDefinition, Matlab, Names, Save, Translate, VisualBasic] cg0 = A; Without any generated code. So if anyone could suggest anything I will be appreciating.

Two questions, please excuse the sloppy explanations - FIRST: If I do the followig: myArray := array(1 .. 5): myArray[1] := 4 myArray[3] := 5 How do I find out which elements in the array are empty? I can't seem to get something like IsZero to work for this even if I load ArrayTools and use Array instead. For example something like: for i from 1 to 5 do if myArray[3] is !empty then print(myArray[i: end if od SECOND: Is there a way to dynamically resize an array? For example, to make something like the following work, starting with an array with a single element: myIndex:=0
