Hi Dr. Kamel Boughrara,

I have question regrding the analytical solution in section 3.3,  I am attaching a file.   Question is regarding  the programming you did, does it has any effect on the solution.  Because i tried to change the values for p, and other variables but could't see the effect.

Also wht the following variable means;

Hi i´m writing a paper about math and i use maple 10 and M. Word 2007 for it, i started with a Laptop with Windows 7 and when i finished it, i open the archive in a desk computer having the same especifications  i notice that the images of ecuations were altered changing "+" and "-" for "C´s" and "K´s", i tried a lot of computers with others especifications and my problem still the same, i changed the format and other stuff but i can´t...

My problem is the following:

I need to add the elements of a matrix (300 by 2) of real numbers  in such way that i will get a new list of elements each one of which will be defined as the sum of all the previous elements plus itself (i mean the elements found in the first matrix).

To make it more clear i want with that way to get results for an intergration made by the trapezoid rule which is not applied to a function but to a list of values stored in a...

Let's consider the following functions:

1/x,1/(exp(x)-1),1/sqrt(x)-all have a singularity at x=0.All got almost similar plot.Now,making the decision if the integration blows up or not at x=0,just by looking at the plot could be misleading.So after integration from 0 to a finite value,say 1, Maple provides the answer-the first two diverge,the last one converges to 2.Now how can I be certain that Maple just simply didn't make a mistake about the first two?Is there any...

Hi all,

For example, I have this equation:

restart: eq:=diff(theta(t),t)*y(theta(t))+x(t)=sin(x(t));

and

wm:=diff(theta(t),t);

I want to replace in eq, wm:=diff(theta(t),t). I used commands eval, subs as:

subs(diff(theta(t),t)=wm,eq);

eval(eq,diff(theta(t),t)=wm);

but with no result

Thanks for any suggestion

Hello,

I am trying to plot the normalized stress values for tension and shear and I would like to reverse the range of the abscissa (x-axis) values for one of the stress values.  The normalized stress values I am interested in are calculated by dividing the calculated stress value by the yield stress for the material in question.  For example, a calculated tension stress of 10 ksi in carbon steel (yield stress = 36 ksi) results in a normalized stress value of 10/36 = 0.27.  I am not having any difficulty normalizing the values; however, I do not see where I can reverse the range of the plotted values from high to low.

Thank you for your assistance.

Kind regards,

I have a for loop which run 50000 times.

I have a dual core cpu made by amd, so parallel is a better choice.

There are two packages in Maple 15: Grid and Thread.

I want to know which one is more effeciency?

And in my program,there are no intersection between for-loops.

how to programming in parallel?

Thank you in advance.

Does anyone know of a working link to the worksheet for this Application Center item?

This is entitled, "Comparison of Multivariate Optimization Methods" and according to the html version it was authored by Sergey Moiseev (who I believe uses the handle mois here on Mapleprimes).

The link to the .mw is broken at that App Center page. And...

Greetings Everyone,

I was looking at the the BlackScholes application worksheet (just search for "black" in the help file), and it has a neat little Monte Carlo simulation block.  I was just wondering if there is anyway to view the underlying code that it's using so I could study it.  Does anyone know how to do this?

Thank for your help anyone.

Billy.

P.S.  I'm using Maple 14.

Hi all

I need to find the fourier coefiicients.  In the following Maple program I get the fourier transform of the signal which is fine, BUT actually I am interested in finding A0, An and Bn of the signal denoted by Plot(f(t),t=0..2*Pi);

step:= 2*Pi/2000;
   start_point1:=Pi/3+Pi/6;
   duration1:=Pi/3;
   start_point2:=4*Pi/3-Pi/6;
   duration2:=Pi/3;
   f:= t -> piecewise(t >= start_point1...

Hi
 How to translate the following lines of commands from Matlab to Maple?


n = 2^10;
M = zeros(n);

I = 1:n;
x = I-n/2;
y = n/2-I;
[X,Y] = meshgrid(x,y);
R = 10;
A = (X.^2 + Y.^2 <= R^2);
M(A) = 1;

imagesc(M)
colormap([0 0 0; 1 1 1])

Gracias

Hi all, 

I need help to run a MATLAB program in MAPLE and find the fourier series coefficients like a0, an, bn.........the matlab code is as follows:                ( to be honest i don't know what format to use in MAPLE for programming?)

clear

step=2*pi/2000;

theta=0:step:2*pi;

start_point1=pi/3+pi/6;

I know Maple has/had opensource ideas behind it, that's why

interface(verboseproc=3)

print(sum)

allows seing source code for function sum, but what if I want to see the source code for local procedures in Statistics module,

for example

print(Statistics[Distribution])

>proc() local T; try if type(args[1],':-ProbabilityDistribution') then if nargs=1 then return eval(args[1...

I am trying to translate the following Mathematica code into Maple, but am having a lot of difficulties finding the equivalent commands.  Could you please help?

Table[ Partition[ Take[ Flatten[ t ], {k, 3*Length[ t ], 3} ], cols ], {k, 1,3} ]

Note: t,k, and cols are all variables

I'm trying to create Skewed Normal distribution with the following PDF

 

sqrt(2)*exp(-(1/2)*(x-mu)^2/sigma^2)*(1/2+(1/2)*erf((1/2)*(alpha*x-mu)*sqrt(2)/sigma))/(sqrt(Pi)*sigma)

 

I'm using the following command for that (referenced from http://en.wikipedia.org/wiki/Skew_normal_distribution
