MaplePrimes Questions


I have the equation to calculate the legendre functions , but i am trying to find a way to form a loop so it would be less time consuming to find for a series of values.

Pn = sum((-1)^i*factorial(2*n-2*i)*x^(n-2*i)/(2^n*factorial(i)*factorial(n-i)*factorial(n-2*i)), i = 0 .. (1/2)*n)

 

This is the general equation , as you can see there are different values of P like p0,p1,p2,p3...depending...

Hello!

I am rather new to maple and have a few questions considering one of my programs.

1. In my program I use 9 nested for loops. Despite trying to figure something out, I couldnt come up with a way of using less for loops.

2. In some of the for loops I want to start the loop from a variable of the for loop above it. Maple doesnt seem to be very happy about this.

3. I want to make a list of all the results produced by the for loops. However...

Hi- I'm having trouble figuring out how to combine two separate DEplot graphs into one graph that represents the SUM of the two.  Not two separate DEPlot graphs in one figure, but the sum of two DEplot graphs in one figure.  I'm using Maple 14- anyone know how to do this?  It's probably simple, and I'm just missing it.  Thanks in advance.

Having overcome a Java VM problem, I have a further problem which is now
limiting my use of MAPLE 14 on Vista:  plotting is limited to plots with
relatively few points or graphical content.

Here is an example in MAPLE 14 (in classic and the normal modes):

> with(RandomTools):with(Statistics):
> N:=400;
> rlist:=(Generate(list(float(range=-1..1),N))):
> plot(rlist,color=black,thickness=1);

This works fine up to N=170,...

m1:= [[1, 2, 3], [ 4, 5, 6], [7, 8, 9]]:

m2:= [[2, 2, 3], [ 4, 5, 6], [7, 8, 9]]:
latex(Matrix(m1));
latex(Matrix(m2));



Hello,

Given my commands (above), I would like to save the output of

latext(Matrix(m1))

as

m1.tex

in the directory "c:\users\desktop\work"

 

and the ouput of

latex(Matrix(m2));

as m2.tex

in the directory "c:\users\desktop\work",

How could I do that?

Hello:

I would like to be able to extract data from a plot strucutre. So say I've done:

p:=plot([sin(x), cos(x)],x=0..1, legend=["sin","cos"]):

display(p);

now I can see the raw strucuture with

lprint(p):

but not quite sure how to extract two lists of tuples that contain the data. I would also like to extract the two items in the legend.

Does anyone know how to do that??

thanks.

eqn1:=(1-x)*exp(c*d*M*z + a*(1-d)*M*y+(M/2))-x*exp(-c*d*M*z - a*(1-d)*M*y - (M/2))=0;

eqn2:=(1-y)*exp(a*d*M*x + b*(1-d)*M*z+(M/2))- y*exp(-a*d*M*x - b*(1-d)*M*z - (M/2))=0;

eqn3:=(1-z)*exp(b*d*M*y + c*(1-d)*M*x+(M/2))- z*exp(-b*d*M*y - c*(1-d)*M*x - (M/2))=0;

 

When I try to solve this system of equations as:

solve( {eqn1,eqn2,eqn3},{x,y,z} );

or 

solve( {eqn1,eqn2,eqn3,0<x,x<1,0<y,y<1,0<z,z<...

Hello:

I am trying to be able to solve my plots into a file programatically (not via right click/export).


when I do this:

p:=plot(sin(x));display(p);

plotsetup(default):  #optional - just to be sure start off at default.
plotsetup(ps, plotoutput="test.eps", plotoptions=`portrait,noborder`);
display(p);

things work ok

BUT.. doint this:

Hello all,

I'm sorry that I'm just not very good at working with Maple's optimization tools, but I appreciate your willingness to work with me. So, this is all related to the same problem I had been working with a few months ago. I used the "operator form" of NLPSolve to minimize the squared residuals of a temperature distribution with an external dataset by changing a few...

Hello,

I do want to export as  LATEX input (displaying only 3 digits) my matrix "tableau".

After using

latex(  evalf(tableau),   3 )

I get too many decimals. What should I do to send as latex input only 3 decimals. My commands are below and my worksheet attached.

Thanks in advance for any help,

Hello,

It is obvious why my command

interface(precision=3) 

is not working?. I get 10 decimals(commands below and output in attached file).

I hope it is easy to fix.

 

Kindest regardsSSSzzzz

Hello,

I'm making a simple for loop with a few lines.  I just figured out how to Shift + Enter to go to a new line without yet executing.  How do I indent my code on the next line, like in every other programming language ever made?  The Tab key does nothing.

Thank you.

Suppose N numbered cars start a race with starting positions N < ... < 4 < 3 < 2 < 1, car number 1 starting in front. (the car's index is the position on the starting grid) The race covers a total of L laps.

If two successive cars are in the position i < j, the probability that i overtakes j within 1 lap is P(i,j). This probability is independent of the position on the track and is constant throughout the race. For instance, if the starting positions...



Hi:

I have justdiscovered that the following "simplify" command gives the wrong answer on Maple 11. Could someone please check to determine if Maple 14 does any better?

> S1:=Sum(1/GAMMA(j+1)/GAMMA(2-j)*GAMMA(1+a-c+j)*GAMMA(1+a-b+j)/GAMMA(a-
> 1+j)*GAMMA(-2+b+c-j+n-a),j = 0 .. 1);
> Ans1:=simplify(S1);
