Hello,

I have a grafic, a power curve, and a few values of the curve.

The values are in 0.5 steps. I would like to calculate the values for all the 0.1 steps.

For example:

I know the values for 4, 4.5, 5 etc. and would like to find out the values for 4.1, 4.2, 4.3 etc.

Is this possible using Maple?

Best regards,

Calin

When I plot csc(k*x) for various values of k, the timing varies considerably depending on the value of k.

Here are the timings for k = 1..5 (note the strange case of k = 3):

  seq(time(plot(csc(k*x), x = 0 .. 2*Pi, -3 .. 3, discont = true)), k = 1 .. 5);
               0.031, 0.031, 14.133, 0.046, 0.062

For k = 6, the time is apalling:

Just for fun, I've created a Pac-Man using Maple's plot command:

body := plottools[pieslice]([0, 0], 5, (1/6)*Pi .. 11*Pi*(1/6), color = yellow):
eye := plottools[pieslice]([-1, 2], .5, 0 .. 2*Pi, color = black, filled = true):
plots[display](eye, body, axes = none);

The hairpiece for Ms. Pac-Man can be added easily:

Continuing on in this series of posts, here is a way to test the randomness of a sequence of bits from a PRNG that is the appropriate to the first morning back after the August long weekend.  It is a very fast, and not very formal test done by checking how well a sequence compresses. This is really easy in Maple 14, with the new commands ?StringTools:-Compress and StringTools:-Uncompress which use ...

I was wondering if anyone has any experience with conic optimization (ie Mosek)
to solve large scale portfolio optimization problems. It all seem so complicated.
It should be possible to call such an optimization engine from Maple right?!

Hi

I'm looking for this application : "A Double Pendulum Model using DynaFlexPro and Maple"

Does anyone have it ?
Indeed,it's no more on this site : http://www.maplesoft.com/applications/view.aspx?SID=1682
I really need to make a simulation of the motion of a double pendulum, using Maple.

hi

I have got an eq: Curl(A)=B;

Both A and B are vectors,  for example,             

A(x,y,z):=Ax(x,y,z) _i+Ay(x,y,z) _j+Az(x,y,z) _k;
B(x,y,z):=Bx(x,y,z) _i+By(x,y,z) _j+Bz(x,y,z) _k;

can I get A as a funtion of B? if I can, how to deal with it, and if not, what other known conditions should be added to solve it?

any help would be appreciated@。@

Dear All,

I have the following data file

1.1    0.751    0
1.5    0.764    0.419
2       0.777    0.665
2.5    0.796    0.791
2.71   0.81     0.81

and I want to plot the 2nd column vs the 1st and the 3rd vs the 1st on 1 axis, with the 1st column on the x axis.

Hi,

I just purchased the personal edition of Maple 14. It was working just fine for 3 or 4 days but now the java interface is distored. Even hovering the mouse over the palettes or images causes distortions. I've uninstalled and reinstalled several times but it hasn't worked.

Has anybody else encountered this? Does anybody have a solution?

Dear all,

 I have a problem in programming with maple if statement:

 restart;Qs:=24; p:=20; m:=3; q:=Qs/(2*p*m); if (q=1) then
> yc:=Qs/(2*p); elif (frem(q,1)~=0) then if (evalf(Qs/(2*p))<1) then
> yc:=1; else yc:=floor(Qs/(2*p)); end if; else yc:=round(0.8*Qs/(2*p)); end if; 

The result is yc:=0; the result must be yc:=1;

 In Matlab:

Hello all,

I'm a new user, hopefully you can assist me as I have work on this problem for quite sometime, I keep getting error of Error, (in dsolve/numeric/bvp/convertsys) unable to convert to an explicit first-order system

I copy my work here. If anyone need the original worksheet I can send this immadiately. Please help and I would like to say Thank you.

R:= 8.31434;             ...

Compare the results of isdifferentiable on 3 piecewise defined expressions f, g, and h.

The first time the order of the asking is f, g, h. The second time (after a restart) the order is h,g,f.

The results are remarkably different! What is going on?

isdifferentiable was first brought to my attention within the last week or so, maybe it is not reliable?

If you remove all the lines with 'assuming' then the inconsistency remains.

Hi all,

What is the command in Maple which is equivalent to the command "mod" in Matlab ?

Thanks

Hello, does soomeone knows how to calculate:

∫ BesselJ(ε, η x) x^n dx
∫ BesselY(ε, η x) x^n dx

and/or

∫ BesselJ(ε, η x) x exp(-a x) dx
∫ BesselY(ε, η x) x exp(-a x) dx

ε and n are positive integers

a is a positive non-integer

η is a positive non-integer imaginary number

Thanks!!

 Hi

I want to solve this Problem

Symbolic_Matrix.pdf

 in symbolic by maple, but i can`t.

is there any symbolic solution by maple or not,

if there is another solution please help me.
