It is a problem which exists in my mind for a long time. Can any one give me some advices? Thank you!

Best regards!


Hi guys,

I've a simple question, can I run a maple mpl file with options? I mean, instad of

maple file.mpl &


maple file.mpl --option1 value 1 --option2 value2 etc &

If yes, how do I instruct the code about what to do with those options, eg assign them to variable?






How to output the solution given by pdsolve as a *.csv or a tab delimited text file?

Maple has got to really work on its help documentation.

Thank you,


with plots

Eq[1] := 5*(diff(f(eta), `$`(eta, 3)))+(m+3)*f(eta)*(diff(f(eta), `$`(eta, 2)))-(2*m+1)*(diff(f(eta), eta))^2-(2*(2*m+1))*h(eta)-(m-2)*eta*(diff(h(eta), eta))

Eq[2] := g(eta)-(diff(h(eta), eta))

Eq[3] := 5*(diff(g(eta), `$`(eta, 2)))/Pr+(m+3)*f(eta)*(diff(g(eta), eta))-5*m*g(eta)*(diff(f(eta), eta))

BCs := [f(0), (D(f))(0), (D(f))(18), g(0)-1, g(18), h(18)]

pars := {Pr = .1, m = 0}

for i to 3 do eq[i] := subs(pars, Eq[i]) end do

I myself have written some programs of math in Maple (e.g. ABC.lib, ABC.ind,
Who could help me how to upload these programs for everyone using easily without downloading and setup them? Thank you so much!

Dear all,

I wrote some simple functions in Maple 13, called "myproc" file,

and used startup code (edit-->startup code) to initialize it in a worksheet by: read "myproc";

Now I am using Maple 14, it does not work, says, "unable to read", sort of thing.


I have also tried to rename the file to myproc.m and read "myproc.m";

does not work either.

Is there any compatibility problem?



I want to call Maple from Excel, this works so far. Problems in the attached Excel sheet:

- The result of a Maple command (components of a vector) will not be placed into separate cells. How can this be done ?
- To auto-update the solution when changing the input matrix, for each component of the solution vector the complete matrix needs to be recalculated. Surely, there is a better way to do this. 


there are several method to provide solve recurrence problems  in Maple,such as define ,rsolve, ,i meet a problem.

i want to compute the function Gamma(n), if n is a posint ,only given recurrence relation f(z)=(z-1)f(z-1),initial condition,f(0)=1,then i can get the true result with rsolve,of couse,i had made  an ansatz that z is n::posint.yet ,z is not posint? To suppose z  equal to 5/2, (2*n+1)/2 more generally,how can get the answer((2n-1)!!*Pi/2^n).

How to graph a function f(x)=x^2-8x+20. Then use Maple to find all the real and complex zeros?

I have a small Maple program which is manipulating lists which have a habit of becoming too long for maple to handle, which yields the error "


The appendant is a figure I generated in a leisure time a fews days ago. There exist 3 problems, I feel they are a  challenge to me. The third problem is:How to rotate the figure automatically? Like this. Can you give me some advices? Thank you very much! Best Regards!

I am trying to calculate inverse laplace of a 3*3 matrix (answer1 matrix). Find below the maple commands i used.

 Hi mates!

Can anybody tell me - is there in maple something like Paskal's begin and end for if-operator?

big thanks in advance)

what I dont understand is the purpose of the second order cone constraint.

The definition is: The first element must be at least as large as the Euclidean
norm of the remaining elements. The euclidean norm for R^3 is the distance from
origo to the point [x,y,z] due to pythagores theorm ie A^2+B^2=C^2 where
C is the distance from origio to the point[x,y,z]

Again for R^3 then we have [x,y,z] then x > the euclidean norm for (y,z) which
means that x> sqrt(y^2+z^2...
