MaplePrimes Questions

Hello all,

I'm working through an optimization problem, and I'm running into a problem adding constraints on the variables I am trying to optimize. I'll attempt to ask the question in a general sense, but if it's not clear, I'll be more specific.

I have a procedure called EIG that calculates the sum of the squared residuals of a model compared to experimental data by inputting 6 variables. I'm trying to minimize this function by using the Optimization...

If you work with Maple on a daily basis sometimes you come across
things that seem impossible to do. Yesterday I tried to have two colors
in a histogram ie -3..-1 = red and -1..3 =blue but I could not figure
out how to do it...hummm.....any suggestions?

 

restart:
with(Statistics):
with(plots):

n:=5000:
A:=Sample(RandomVariable(Normal(0,1)),n):

Histogram(A,bincount=100, color=blue);

I don't quite understand about some parameters of flexible beam. Please introduce  briefly.
 
1. Truncation order of inertial terms
2. Truncation order of elastic coordinates
3. Number of elastic coordinates

help_for_maple_quest.docplease give a explain how to work for operations.

    

 

 I would like to select the color of the arrow for T,N and B.

Thank you for any suggestions.

Hello all,

I have a little problem with an expression I have to develop in taylor/series.

Here it is:

sinh(sqrt(omega/nu+m^2)*h)

I want to develop it in "nu", giving that "nu" is a small parameter, and it says that it doesn't exist a series expansion.

But when I can obtain the series expansion of the "sqrt" part only of the expression, which yields:

E.g. I want to modify the Binomial distribution in a way, that k is not the number of successes, but the outcome.

Let's assume each success wins $100, while a failure results in $0.

My thought was to substitute k for k/100, but that produces an error message.

Can anyone tell me, how to implement that in Maple?

 

Thanks a lot.

Hi,

i use fsolve to find appraxmaite solution. there are some parameter in my equastion wher i do loop in this pramater form 0.. 1000,000,00

i have other problem with "fsolve and digits". when Digits =12;  i cannot find  approx solution using "fsolve"

when i decrease or increase  the digit "Digits:=11 , Digits:=13",  i find the  approx solution using "fsolve".

i donot know what is wrong!!!

Hi all,

I have Maple 11  ( Student Version - I am a UC Berkely Distance Learning Student ). I need the Dynamic Systems Package, can I down load it and install it in my Maple 11 install ?? If so how ??

 

Thanks,

There was an interesting question from Christopher2222:

Maple keeps changing the variable xi to the greek letter

Now I need a solution for a specific application, Here is the code:

with(Statistics):

L:=[Normal, Beta, Gamma]:

for i to 3 do
f[i]:=RandomVariable(L[i](4,2):
end do:

This will work for L[1], but not for L[2] and L[3]...

hello all, I'm trying to solve ODE's but my computer takes a very long time evaluationg. and still not giving an answer for more than 4 hours.

so please is there anything error in my solution

deqs := {NULL
         , diff(u2(y), y, y)-((h^2/K)+m*h^2*M^2)*u2(y)+m*b*rho*h^2*GR*(c3*y+c4) = 0
         , diff(u1(y), y, y)-((1/(K*(1+k1)))+(M^2/(1+k1)))*u1(y)+k1*(diff(N(y), y))/(1+k1)+GR*(c1*y+c2)/(1+k1) = 0

I am not able to format the number along the axis of a 2D plot to use period as the decimal separator - and not to have different number of positions after the decimal on the x- vs. the y-axis either.  I have set the Windows language/region to the US.  Anyone who might help?  Regards,

 

Let's say I define L1..L5 and M1..M5 respectively

for i to 5 do:
L[i]:=(-i^2+6*i);
end do;

for i to 5 do:
M[i]:=(-i^3+18*i);
end do;

Now I want to find out, whether the maxima of the two sequences L1..L5 and M1..M5 have the same subscript.
So I need a kind of proc that outputs 'true', if subscript(max(L1..L5))=subscript(max(M1..M5)), 'false' for subscript(max(L1..L5))<>subscript(max(M1..M5)) and 'FAIL' otherwise.

Does anyone...

Greetings:

Anyone know how I can print the code of the Tutorials of the Maplets?

 I need take it as a guide to developing themselves because I don't dominate so much the Maplets management and I need...
