tekssifer:=Qnuux*#Huh

Hi, how i need to continue my command to get the size of tekssifer in bytes? 

Thank you~=]]

Before version 2016 Maple was incredibly good at evaluating an infinite power series and returning a simple function, e.g. 1/(3x+2).  Now version 2016 just returns the input sum expression with no change.  Is there some new command to get the old results?

Good day everyone, I would like to know how to work this out in a code on maple:
-I have some vectors (K(1),K(2),K(3) etc) similar to this:

K(1)=[A B C]

-I want to sort all of them by the value of C, but when I use the sort built in comand the program return a answer based on K index instead a sorting based on C.

Any ideas would be higly apreciated.

i want to solve these two coupled eqaut with finite boundary conditionsions. Can some one help me

eq1:=diff(f(eta),eta,eta,eta,eta)+2*(epsilon/(1+epsilon*theta(eta)))^2*diff(f(eta),eta,eta)*((diff(theta(eta),eta))^2)-(epsilon/(1+epsilon*theta(eta)))*(diff(theta(eta),eta,eta))*(diff(f(eta),eta,eta))=0;

eq2:=diff(theta(eta),eta,eta)+Pr*Re*f(eta)*diff(theta(eta),eta)=0;

Re:=1:Pr:=1:epsilon:=0.25:

bc:=f(1)=0,D(f)(-1)=0,D(f)(1)=1,D(f)(-1)=1,theta(-1)=0,theta(1)=0;

I have a column matrix with all the elements 1.

A:=Matrix(100, 1, 1):

I want to generate another matrix B exactly same as A but with one element changed and keeping all other elements to be same. Manually, I could do by following way:

A[1,1]:=1.1;
A;
B:=A;

But I have to do this with each of 100 elements of A. For instance, in step 1 I want only the first element changed into 1.1. In step 2 I want only the second element changed keeping all others to be 1, and go upto 100.

Could anyone give me an easy way to do this? I would like to appreciate your help in advance.

How can Maple solve that problem for me?

Given: a summation of one equation with its limits, equaling another summation with given limits, but NOt the equation. How do Maple be programmed to find that out? 

fx     [sum(x^(n)*y^(1-n), n=0..10, = sum(unknownequation),n=1..11)]   , find the unknown equation by maple?

Appreciating in advance,

Wanna ask that how to make maple program to select a random binary number in base 2.

For example, suppose that we have a value 11101100(8 bit which in base 2),then how to let Maple to select a binary number randomly and the binary bit of the random number always shorter than the previous then sum it together?

For example the program will select 1101101(7-bit) and sum it together(11101100+1101101=101011001,in base 2)

Can somebody help me thanks.

Hai everyone, wanna know that how to perform 2's complement method in maple 17?

For instance, 2's complement of 19 is 11101100(in base 2) in 8-bit binary representation.

Hello everyone,wanna ask that how to perform binary arithmetic(addition,subtraction,multiplication and division) in Maple.

For instances, how i need to perform:

1101+111=10100(all in base 2)

11000-1011=1101(all in base 2)

1011*1101=10001111(all in base 2)

10010011/1011=1101(all in base 2)

Kindly help,thanks.

Hi all,

I am trying to do some calculation using Maple. I have different expressions containing some power of y. I would like that Maple automatically substitutes y^4 = f(y), in each one of these. So for example, if my expression contains y^5, I want it substituted by y * f(y), and so on. How can I do?

Hi all,

I'm trying to perform some calculations containing exponential integrals. Here is a snippet of my code:

restart;

H:=0.5:

q[0]:=10^5:
Es := 4*10^9:

p[0]:=10^6:
q[s]=10^10:

C := (q) -> q^(H+1.5):

G := (q) -> (int(q^3*C(q), q = q[0] .. q)):
P := (q) -> 1/sqrt(G(q)):

p := (xi) -> p[0]/P(xi*q[0]):
w:= (q,xi) -> 1/(Pi*(int(C(qs)*qs^3, qs = xi*q[0] .. q)))^(1/2):

U := (xi) -> (int(q*C(q)*w(q,xi)*(Int(exp(-(w(q, xi)*ps/Es)^2)/ps,ps=p(xi)..infinity)),q=xi*q[0]..q[s])):

My objective is to evaluate U for a set of discrete values of xi for further processing e.g. visualisation via plots. Neither value(U(xi)) nor evalf(U(xi)) produces a numerical result so I keep searching for solution. Does anybody have an advice how to solve U?

Regards, lassa

Hi, I have defined two functions:

ex1 := (x,t,z) -> -1.132*10^(11)* exp(9.9*10^(6)*x)*exp(sqrt(-1)*(1.95*10^6*z-2.98*10^15*t))

ex2 := (x,t,z) -> -2.82*10^(12)* exp(2*10^(6)*sqrt(-1)*x)*exp(sqrt(-1)*(1.95e*10^(6)*z-2.98*10^(15)*t));

And then tried the command:

implicitplot3d( ex1, x = -10..0, t = 0..10, z = 0..10, axes = boxed, style = patchcontour, scaling = constrained, shading =z);

But the boxes are entirely blank! What is the problem here?? It should be some kind of sine curve

Maple 2016.

Why does

int(sqrt(c+d*tan(e+f*x))*(a+b*tan(e+f*x))^(5/2),x);

Causes mserver.exe to hang into a loop at full CPU and maple hangs?

Windows 7, 64 bit.  Even using timelimit() on it, it still hangs exceeding the time limit and never return. I have to kill mserver.exe or exit Maple to recover.

A quick question, Can I add legends to 3D plots? 

I am currently working in Maple, following an example on the Maplesoft site very closely. I am trying to make use of the 'Colorize' function in the Escape-Time Fractals package.

I have a Newton's basin with the standard colouring but am trying to make my image more sophisticated. I have tried following the example given for the Mandelbrot set (At the bottom of the page - http://www.maplesoft.com/support/help/Maple/view.aspx?path=Fractals/EscapeTime/Mandelbrot) as there isn't one on the Newton Fracal page but keep receiving the Kernel lost message. I do not think the issue is my firewall.

My code is as follows,

with(Fractals:-EscapeTime);

with(ImageTools);

Everything works up until I go to evaluate P. I have tried giving both Arrays datatype=float[8] and have tried getting rid of the datatype section completely as to use the default. Neither of these have helped.

Any insight as to why this may be happening would be appreciated.
