MaplePrimes Questions

I have a function i want to plot on the interval 0..15. The function takes the trunc of the input but when I plot I don't actually get 16 individual plots, I get 'mini clusters'. Is it possible to fix this? Thanks
how do i go about finding all the polynomials of degree 5 or less that satisfy this equation? i found the two obvisous families of the solution to be y=a and y=bx, where a and b are constants.....

Dear Maple experts,

I'm trying to make use of Maple's external calling facility to speed up some bottlenecks in my calculations (and simply to learn how it works...).

As I frequently need complex numbers, Fortran looked like the more appropriate choice. This is mainly because Maple can help with generating small code snippets for complex-valued functions whereas the code generation for C/C++ requires more manual work...

Although my calculations are somehow complicated, I don't think that's normal so I finally stoped it.

What are possible solutions? or shall I give it more time?!

Let be q(x) some polynomial of degree = 2 in several, n variables x[i],
x to be thought as (row) vector

Can Maple provide the quadratic normalform for q (real resp. complex)?

By this it is meant that q ° f (x) equals one of

  Sum( c[i]*x[i], i=1..n)
  Sum( c[i]*x[i], i=1..n) + 1
  Sum( c[i]*x[i], i=1..n) + x[n+1]

where c[i] in K, K = Reals or Complex (should not matter so much, except
char(K), and square roots have to exist, so Rationals(squareRoots) is fine),
and f: K^n -> K^n is affine ( = bijective and linear + shift vector)?

<p>I have a 1-dimensional list in the form of  data := [1,2,3,4...]. There are 5000 elements in this list, and only about 2000 don't repeat anywhere else in the list, the other 3000 do. What I want to do, is plot the number of times a given element repeats vs what that element is. For example, if an element with the value 5 is repeated 12 times in the list, than I want 5 on the x-axis, and 12 on the y axis. </p>
<p>I am using Maple 11. Can anyone help?? Thanks!</p>

Hi all,

I  have problem about translate from maple to C Language. I do project about cryptography, now I can write command in Maple. I don't know how to translate to C language

How should i do?

Anser me please.

Thank you so much.

Hi all,

I have a base rectangle with the size bx * by  and several rectangles which have all the same size ax*ay but can be arranged horizontally or vertically (ay*ax).

Is there a way to calculate the best arrangement?

 

How can i get a bifurcation diagram and also identify the types of bifurcation that occur for these equations: 1) fa(x) = a + ln(x) , x>0 2) fa(x) = a - ln(x) , x>0 3) fa(x) = a * ln(x) , x>0 4) fa(x) = a + x - exp(x) , x>0

How do I plot the output of the Maximize command?

For example, here's a function that determines the value of x in the range [0,3] at which a particular fuction is maximized:

with(Optimization);

f := (x,t) -> -x^2+3*t*x-1

fmax := t -> rhs(Maximize(f(x,t),x=0..3)[2][1]);

How do I switch the autosaving off?

Hello! I am trying to create a double exponential smoothing model by optimizing the parameters a and b. The model is quite big and Maples needs a very long computation time. Can anyone help me on this one? I'll attach my file: View 9101_double_exponential_smoothing.mw on MapleNet or Download 9101_double_exponential_smoothing.mw

Hi

I am seeking a generalized collect command in Maple to collect a expresion W

W:=mu[1]*mu[3]^3*sin(mu[1]*Pi)*cos(mu[2]*Pi)*sin(mu[3]*Pi)*cos(mu[4]*Pi)+mu[4]^3*mu[3]*cos(mu[1]*Pi)*cos(mu[2]*Pi)*sin(mu[3]*Pi)*sin(mu[4]*Pi)-mu[3]^3*mu[2]*cos(mu[1]*Pi)*sin(mu[2]*Pi)*sin(mu[3]*Pi)*cos(mu[4]*Pi)-mu[4]^3*mu[2]*cos(mu[1]*Pi)*sin(mu[2]*Pi)*cos(mu[3]*Pi)*sin(mu[4]*Pi);  

to two different expresions W1 and W2 as

W1:=mu[3]*cos(mu[2]*Pi)*sin(mu[3]*Pi)-cos(mu[3]*Pi)*sin(mu[2]*Pi)*mu[2];

Hi there,

I'm having a problem when attempting an implicitplot of an expression containing an integral.

Here is a minimal example of what I'm trying to do:

restart: with(plots): with(DEtools):
f:= t-> t^(-2);
F:= x-> Int(f(t), t=x..1);
G:= (x,y) -> evalf(F(x)-y): G(x,y);
implicitplot(G(x,y), x=0..1, y=0..1);
plots[implicitplot](G(x,y), x=0..1, y=0..1, grid=[100,100]);

The above results in the following error message:
