My code works in Maple (18.02), not Maple Player (2015.1). Much headache ensued.

I've isolated the problem in a toy form:

Defn := proc (scaleby)
whattype(scaleby);
end;

Explore(Defn(p), parameters = [p = [1, 10, 100]]);


In Maple will return "integer" for any value of p selected in the combobox.

In Maple Player returns "string" for any value of p selected in the combobox

Is there something I'm missing here? Is Maple Player not backwards compatible to versions of Maple prior to 2015?

My understanding is that Maple Code should export without headache to Maple Player. Is this a solid understanding?

Thanks for helping out a newbie!

Is Maple 18 student version CUDA enabled? I am getting when I tried CUDA:-IsEnabled();

Error, `CUDA` does not evaluate to a module

thanks

I have an expression like this (from an earlier computation):

2*(sum(A*cos(omega*t)^2+cos(omega*t)*B*sin(omega*t)-cos(omega*t)*ymeas(t), t));

I want to distribute the sum over the terms in the expression, i.e.

sum(A*cos(omega*t)^2,t)+sum(cos(omega*t)*B*sin(omega*t,t)+sum(cos(omega*t)*ymeas(t), t)));

I suspect defining a rule and using applyrule should be the way to go, but for the heck of it I can't figure how to do it. The best I can manage is getting the Maple kernel hung with the following construct:

distSum:=sum(A::algebraic+B::algebraic+C::algebraic,D=algebraic)=sum(A,D)+sum(B,D)+sum(C,D);

applyrule(distSum,(5)); # (5) referrs to the expression on line 2 (and it is a proper label in my Maple wrkbook).

I have asked similar questions before and gotten answers; but I am not able to find what I need in MapePrimes (or my faorites, for that matter).

Thanks for any help,

Hi everyone,

I would like to use structs

    struct sname {
        smem1;
        smem2;
    }

in my C code defined elsewhere. How do I get CodeGeneration to produce variable names like

    sname.smem1

?

The appoach to use the respective maple data type

  sname := Record('smem1', 'smem2'):
  CodeGeneration[C](sname);

results in

    Warning, procedure/module options ignored
    double smem1;
    double smem2;

and the appoach to define it as name

    CodeGeneration[C](`sname.smem1`);

results in

    Warning, the following variable name replacements were made: sname.smem1 -> cg0
    cg = cg0;

Your answer is appreciated

hi everyone,
I wanna to solve this equation using maple 12 but I receive this warning message

cos(x)*cosh(x)=1

cos(x)*cosh(x)=-1

tan(x)=tanh(x)

thanks in advance

how to get maple to do linear algebra in Z_2 (integers modulo 2)

I don't want it to solve and then reduce mod 2 I want it to work over Z_2 so basis([ [1,1,1], [1,-1,1 ]) = [1,1,1]  etc

Greetings,

I need some help/advice because I think I am going crazy..!

I am trying to solve numerically a system of two PDE's. My initial condition is a gaussian and I apply cyclic boundaries.

With Maple 18 and pdsolve/numeric I am waiting a considerable amount of time and the result is a bell shaped travelling wave that increases its height over time. The clush between two such waves leaves them almost unaffected (the big pass through the small one).

With Mathematica 10 and NDSolve the waiting time is almost zero and the result (after few timesteps) is a shock wave travelling with steady height. Moreover, the clush between two of them is fully plastic (the big "eat" the small one)

I double-triple check the equations and the boundary conditions and I assure you that are the same..Any ideas what is hapening? Is there any way to check that the Maple results are correct?

Hi,

I just started to use Maple and I have a question if there exists in it an equivalent function to Mathematica's FindInstance? In general, I have an inequality and I would like to find few first solutions to it.

Hello,

In a worksheet, I don't know why the brackets like this "[" where normally I put my maple inputs and generally before the symbol ">" are not present (or displayed).

1) Are these brackets important for the computation of calculations in a worksheet ?

2) How can I do to display them again?

Thank you foryour help.

I would like to pay attention to an article " Sums and Integrals: The Swiss analysis knife " by Bill Casselman, where the Euler-Maclaurin formula is discussed.  It should be noted all that matter is implemented in Maple through the commands bernoulli and eulermac. For example,

bernoulli(666);

eulermac(1/x, x);

,

eulermac(sin(x), x, 6);

BTW, as far as I know it, this boring stuff is substantially used in modern physics. The one is considered in

Ronald Graham, Donald E. Knuth, and Oren Patashnik, Concrete mathematics, Addison-Wesley, 1989.

The last chapter is concerned with the Euler-MacLaurin formula.


           

Hi,

a researcher at our department starts multiple Maple programs in parallel on our Linux servers.

Sometimes a high percentage of the resulting mserver processes hang. ps shows their state as

SNl (sleeping, multithreaded). strace to the processes shows that every one is waiting on a

futex without timeout. The problem occurs in versions 16 and 18. This is annoying.

Is there a fix for this?

hi I am tying to create a matrix: 

for i from 1 to 5 do

for j from 1 to 5 do

 A[i][j]:=i+j;

od

od;

But it doesn't create a matrix. As when I tried inverse operation it doesn't work. How can I create a matrix? Also can the index start from 0??

thanks

f := x^2*(y/x+sqrt(-7*y^2/x^2))/(y^2*(x/y+sqrt(-7*x^2/y^2)));
v := parametrization(f, x, y, t);

it can not parametrize.

i do not know which book teach group theory and algebraic curve

can we call this algebraic curve over finite field ?

how to represent a function as an algebraic curve equation for parametrization?

When I do simplify(LegendreP(n, 1, cos(t))), Maple gives me -sqrt(1-cos(t))*sqrt(cos(t)+1). Isn't it the same thing as -sin(t)? How can I have Maple further convert/simplify it to -sin(t)? (I tried simplify(%, trig) but it didn't work). I am new on Maple. Thanks in advance for anyone's help!
