Hi,

I have a problem with code generation to matlab. I have a model in maple that I have sampled for som values and I now want to import these matrices.  The problem is that I want to name the matrises "A(:,:,1)","A(:,:,2)",... i.e. "A(:,:,i)", 3d matrices in matlab.

hi all.

I have calculated an integral. the answer is a polynomial containing large power of  parameters ( i.g. x).

how could I reasonably simplify the polynomial? it has a long function too. ( 5 pages)

thanks.

Hi everyone,  to have an example, the following recurrence is given. I want to proof that it converges (and determine the limit for n->infinity).

g:=a(n+1)=3/2+sqrt(1+a(n));

Maple cannot find an explicit  form of a(n), typing rsolve(g,a(n)); gives the input back. One standard approach would be calculating the possible limit by solving the fixed point equation

a=3/2+sqrt(1+a)

this isn't a problem ofc. Further it is necessary to show a(n) is bounded and grows monotonous. So my question is, is Maple a useful tool for mathematical induction ?

HOw to use RSA with the modulus n = 119 and the exponent e = 7, with the 95-character
alphabet consisting of the printable ASCII characters to encrypt the word “Yes”.
so that Y=58, e=70, s=84. ( encryption should be as a list of three numbers.)

Solve using Maple:Twenty-one pirates are dividing their horde of gold dubloons. Since they are a
democratic outfit, they first try to divide the coins evenly, but they find there are 19
coins left over. The “discussion” about how to divide the remaining coins results in
only 16 pirates still needing to divide the horde (the remaining five went to a place
where you can’t bring money or anything else with you). The redivision among
16 pirates leaves 1 coin left over, and three of the pirates make a grab for it. These

I’ve developed a procedure in the Maple as follows:

Hi all.  How do I plot sin(x) such that only Pi/2, Pi/, 3Pi/2 and 2Pi appear on the x axis and the values 0, -1 and 1 appear on the y-axis and the axes x and y appear at the appropriate axes?

Thanks.

Very simple question

I want to plot the function y = f(x) but I want the axes to appear rotated (as I show in the picture)

HOw can i do this??? 

Thanks a lot!

If we run the below code we will get a plot of a pure unit root and the serial correlation parameter for a pure unit root

My question is why do we have such a large amount of serial correlation in a process that is supposed to be random?

I ran a simulation and found that the average serial correlation for a 100 pure unit roots was 0.941

It does not seam right.....am I doing something wrong here?

I thought the basic definition of a random variable was serial correlation=zero.

Hello everyone,

I can't succeed in obtaining the complex conjugate of a function like this:

 suu:=x->( e^(-Iq(x)b)*(cosh(q(x)*b)) )^2 - I*sinh(q(x)*b) * e^(-4iq(x)b)

where q(x) is:

q(x)=sqrt(2*m*(V-x))/h

and m, V and h are respectively mass of electron, 1 eV and Plank constant /2 pi.

what I need is |suu(x)|^2 (where the * stands for product and not for complex conjugate!) but succeding in obtaining the complex conjugate of the function wold be enough.

Can you help me?

Hello:

I am using Maple11 for an Adv. Computer Applications Lab.  I am being directed to use the "implicitplot" function to plot a polynomial, and also plot a previous function that used the "spline" command to plot it on the same graph. 

Can someone please offer a suggestion?

Also, for the polynomial. how do I find all "x,y pairs? " I used the "solve" command to evaluate for 'x' and then 'y'. 

Is this correct?

Howdy,

I am making a maplet that guides a user through crafting a Taylor series equivalent of a function. Obviously this involves finding a formula for the nth derivative of the function. Can Maple calculate this?

I need help with a coursework question. Would be greatful if anyone could help!
the question is: solve this x[i-1] + i*x[i] + x[i+1] = i where i=1,2,...n and x[0] = 0. Give your answer in decimals.

wat method would you use to solve these equations? the code I have put in is:

x[0]:=0:
for i from 1 to 3 do:
  eq[i]:=x[i-1] + i*x[i] + x[i+1] = i
od;
eqns:=seq(eq[i],i=1..3):
sol:fsolve({eqns});   assign(sol);

am i on the right path? is there anything i am doing wrong? if so, what is it?
