Hi,

I'm currently writing my thesis and actually haven't used Maple before.

I've got the following problem with converting the results of a sequence:

seq(Optimization:-Maximize(function with 2 variables), parameter:0..1,0.1)

The results are ok, but I can't convert the values to a spreadsheet with 4 columns (parameter value, maximum value, value of variable 1, value of variable 2).

Thank you!

Best regards

Using Maple 2016, I created a new Document with one line:

A=(1,2,3)

Right-clicking on this expression I thought I could choose Assign to a Name, as is done in Clickable Calculus Series - Part 3: Multivariate Calculus, found here:

https://www.youtube.com/watch?v=GYN-GetHRFA

However, Assign to a Name does not appear in the context menu.

On the other hand, if I write

B=1,2,3

(with no parentheses) and right-click on this expression then Assign to a Name does appear in the context menu.

Any insights on this?

Thanks.

When using seq function below in the second call, it does not generate a sequence of functions with 'a' being 1, 2, and 3, and I had expected.

First seq function call is just to show that it works without the function "x ->" wrapping.

I could of couse use unapply as in the third call, but I had expected the second call to work.

Am I doing anything wrong, or is this a Maple bug?

Hello

Any idea about the summation of Fibonacci sequence

Fibonacci.mw

i'm using maple in a research but i want to add a recursive function h_m(t) in 2 case : if m is integer positive and not, la formule est donnée comme suit : if (mod(m,1) = 0 and m>0) then h:=proc(m,t) local t ; h[0,t]:=t ; for i from -4 to m by 2 do h [m,t]:= h[0, t]-(GAMMA(i/(2)))/(2*GAMMA((i+1)/(2)))*cos(Pi*t)*sin(Pi*t) od: fi: end;and i wanna to know how to programmate a Gaus Hypegeometric function. Thank You

Is there a Maple function that given a set of substitutions in form object=set of substitute objects produces a sequence of sets, each a product of substitution from the next, remove repetitions. An example:

#Substitutionsa = {b, c, d}, b = {a, b, e}, c = {a, d, f};#Resulta = ({e, f}, {b, c, d}), b = ({f}, {c, d}, {a, b, e}), c = ({e}, {b}, {a, d, f});

I need to do this with a sequence of a large number of elements but here is my question with a sequence of fewer elements.

a:={10,11,-13,9,20,74,10}:

I want to check each element of the sequence if it is negative. And if any element is negative I want to replace with 0 (or do something else). I tried the following code but it didn't work.

for k from 1 to 7 do if (a[k]<0) then subs(a[k]=0, a) end if:end do;

Please help me to figure it out.

Hello,

Paraphrasing:

https://en.m.wikipedia.org/wiki/Langford_pairing

given a sequence of 2n numbers 1,1,2,2,3,3,...n,n in which the two 1's are 1 slot apart, the two 2's are 2 slots apart, the two 3's are 3 slots apart, -> generally the two n's are n slots apart.

for n=3, a possible sequence is [2,3,1,2,1,3].

There is sequences for n=4,7,8...

i havent a clue how to write a maple procedure to generate a sequence for given n, but I'm hoping an expert here can.

(Some) prime reciprocals have an interesting property. the repeating sequence has length p-1.

eg 7, has repeats after 6.

1/7=0.142857142857......

17 has repeats after 16

1/17=0.05882352941176470588235294117647059.........

of course some primes don''t have this property....

So what I need the experts here is for some code

myproc(17)=16, (and the sequence) 0588235294117647

my go:pinched from

http://199.71.183.11/questions/39621-Pattern-Matching-In-A-Sequence-Of-Digits

PriDigits := "" || (op(1, evalf(1/17, 50)));

reps := StringTools[Repeats](PriDigits);

lngth := seq(op(3, A), A in [reps]);

the leading 0 (which is part of the sequence) is a problem.....

hi every one, i would like to know if it is possible to implement the following recursive sequence in Maple : q(1) = q(0) +q_dot(0)q_dot(1) = q_dot(0) +q_ddot(0)q_ddot(1) = q_ddot(0)+q_dddot

q(2) = q(1) +q_dot(1) = (q(0)+q_dot(0)) + (q_dot(0)+q_ddot(0)) = q(0)+2q_dot(0)+q_ddot(0)q_dot(2) = q_dot(1) +q_ddot(1)q_ddot(2) = q_ddot(1)+q_dddot

q(3) = q(2) +q_dot(2)=(q(0)+2q_dot(0)+q_ddot(0))+(q_dot(1)+q_ddot(1))= q(0)+3q_dot(0)+q_ddot(0)+q_dddotq_dot(3) = q_dot(2) +q_ddot(2)q_ddot(3)= q_ddot(2)+q_dddot

I would like every q(n) to be expressed as following : q(n)=q(0)+n_1*q_dot(0)+n_2*q_ddot(0)+n_3*q_dddot.

By computing manually some sequences i am now sure that : n_1=nn_2=(n²-n)/2n_3=?? (I would like to find this one)The sequence can be written in a more general way as following : q(n) = q(n-1) + q_dot(n-1)q_dot(n) = q_dot(n-1) + q_ddot(n-1)q_ddot(n) =q_ddot(n-1)+q_dddotCan you guys please show me how this can be implementes in Maple ? Thanks in advance

I have the following question:

Illustrate how the sequence N->R defined by n ->n^2/n^2 + 31n + 228 can be shown to bewithin a given epsilon > 0 of its limiting value x0.(a) use an appropriate conditional statement to find N such that abs (xn - x0) < epsilon for every n>=Nand produce an appropriate list of the data points (n,xn) to illustratethis

I found N but without using any CONDITIONAL STATEMENT.Can you help me find N using IF FOR WHILE?

Hello everyone. Let n be a positive number; I seek how to write the matrix Z\in M_{2^n,n} that is defined as follows:

for every i,j, Z_{ij}\in \{-1,1\}.

When I consider the 2^n rows of Z, I want to find ALL the possible sequences of length n with the entries +-1. A toy example, when n=2, is Z=\begin{pmatrix}1&1\\1&-1\\-1&1\\-1&-1\end{pmatrix}.

Thanks in advance;

How can I have a sequence as follow by using "seq" command?

x1,x2,...x200.

Please note that I need "xi" not "x_i".

I have the following sequence: n^{2}/n^{2}+31n+228.The question asks me to use an appropriate conditional statement to find N such that absolute (x_{n}-x_{0})<epsilon for every n>=N. I found N but i don't know how to find it using Maple17.Can you please help me?

Given the sequence defined by the recursive relation a[n+1] = r*a[n](1-a[n])You need to use the procedure iterate.Throughout this problem you should choose initial values in the interval 0<a0<1.(a) Let r=3/2. Calculate a moderate number of terms in the sequence (between 10 and 20). Does the sequence appear to be converging? If so to what value? Does the limit depend upon your choice of initial value? Plot the terms you have calculated(b) Let r=2.8. Calculate a moderate number of terms in the sequence (between 10 and 20). Does the sequence appear to be converging? If so to what value? Does the limitdepend upon your choice of initial value? Plot the terms you have calculated How does this sequence differ from that in part (a).(c) Let r=3.2. Calculate a moderate number of terms in the sequence (between 10 and 20). Show that the sequence does not appear to converging. Plot the terms you have calculated and describe how the sequence behaves in this case.(d) Consider intermediate values between 2.8 and 3.2 to determine more precisely where the transition in behaviour takes place. Provide a few plots (no more than 4) showing the values you have investigated.(e) Consider the values of r in the range 3.43<r<3.46. Determine as accurately as you can the value of r for which the period of oscillation doubles.(f) As r increase further period doubling occurs. Try to find the when the sequence appears to oscillate between 8 values.(g) Let r =3.65 and calculate a considerable number of terms (at least a few hundred) and plot your values.(h) For r=3.65 choose a0=0.3 and then a0=0.301. Find and plot some terms in the sequence for each initial value. Determine how long the terms in the two sequences remain close together and when they begin to depart significantly from each other.
