I want to evaluate the values of x and y and the data should bo saved in .xls format  from contour plot 

for g=0.1 the data x and y values  should be stored in xls sheet 1  atleast 50 values 

similarly  in separate xls sheet 

for g=0.0 the data x and y values  should be stored in xls sheet 1  atleast 50 values 

with(plots):
g:=y*(1-1/(x^2+y^2)):
colors:=table([0.1=blue,0.0=green,0.2=red]):
display(seq(contourplot(g,x=-1..1,y=0..2,
contours=[i],color=colors[i],axes=boxed,legend=(i)),i=[0.1,0.0,0.2]));

thanks in advance

Dear Experts,

I am novice to Maple 14, to do some numerical work I am using its 2D math input. I am having problem while using an itegral equation with a limit from 0 to infinity, when I use this limit; in answer I got un-solved equatoin instead a numerical value and this un-solved equation have FLOAT value, when I tried with some other input that time maple give answer again 

I have a huge PDE system included reaction-diffusion system with 4 independent and 12 independent variables. I read on the maple help for pdsolve/numeric/method. I found it is only for single partial differential equations in two independent variables. Is there anyone knows the ability of Maple for such a system?

I am trying to solve a square polynomial system (16 x 16, I was able to solve an 8 x 8 fine) using the package RegularChains (with Groebner bases the problem is the same) but I have a memory constraint of 4G in the Linux cluster and my batch job gets terminated after Maple grabs too much memory:

TERM_MEMLIMIT; (job*killed*after*reaching*LSF*memory*usage*limit.Exited, with, true)*(File*size*limit*exceeded.Resource, usage, true)*summary; CPU*time;(4509.00*sec.Max, Memory, true...

How do I install Maple 15 in Windows 8.  I get a requester that says that the GUI version is not supported.

Hi all,

I have the following functions.

restart:
with(IntegrationTools):
N:=4:

i:='i':
for i from 1 to N do
    assume(x[i-1]::constant):
    assume(x[i+1]::constant):
    assume(x[i-1]::constant):
    assume(h::constant):

 phi[i](t):=piecewise(t>=x[i-1] and x[i]>t, (t-x[i])/(h), x[i]

(x[i+1]-t)/(h), 0);

end do;

## my goal is solve the integrals involving phi[i]'s as integrand and x[i]'s as its limits.

i am implementing q-Laplace

http://perso.uclouvain.be/alphonse.magnus/gbang/qbook712.pdf

when there are quite many differentiation rules

how to do a function for a new kind differentiation like a maple do?

1.

qRacah := qhyperterm([q^(-x), alpha*q^(-x)/(gamma*delta)], [alpha*q], q, gamma*delta*q^(x+1)*t, k)*qhyperterm([beta*delta*q^(x+1), gamma*q^(x+1)], [beta*q], q, q^(-x)*t, k);

i use inverse laplace to transform ordinary generating function into exponential generating function

can not further evaluated

2.

i do not know whether x is main variable or q is main variable or both are.

ff := eval(subs(x=0, exponential_genfun));

How to give the different colors in implicit plot  and add legends my codes are 

with(plots):

g:=y*(1-1/(x^2+y^2)):

aa:=[g=0.1,g=0,g=0.5]:

implicitplot({seq(aa[i],i=1..3)},x=-5..5,y=0..2,legend="g=0.1,g=0,g=0.5",color=[red,blue,green],scaling=constrained);

i want to draw  a countour plot and i want the graph in the given below patter  and my codes are 

for Q=1, and Q=2 ,Q=3.2

F:= x^2+2*y^3+Q:
p1:=contourplot( F, x=0..1, Q=1,color=red):
p2:=contourplot( F, x=0..10, Q=2,color=blue):
display(p1,p2):

thanks in advance

Is there a function that will return the current orientation values in a 3dplot, or can anyone help me with this. I would like to display the orientation as I rotate a plot.

TIA

Does anyone know why the scale isn't matching what i asked for here?

a)can someone pls help write code to generate this circle within square, then square within circle....(with the colours)

Its a bit like this problem:

Hi,

I have a trigonometric series which contains 1D and 2D modes. It looks something like the following:

S:= Acos(mx)sin(nz) + Bcos(kz)sin(qx) + Csin(sz) for m,n,k,q,s=1,.....10.

I am iterested in obtaining the amplitudes of the 1D modes (i.e. C in the above expression). Is there a way to do this using the coeffs function? I would like to use this in such a way as to isolate the 1D modes from th series. Any suggestions?

Thanks for your help.

Hi, 

   I'm solving two equations and two unknowns with fsolve where there are multiple solutions (at most 3). I iterate this and my next set of solutions depends on the previous one. The problem is the the first solution (the only one I need) may be arbitrarity close to to the previoius solutions and fsolve skips it and finds the second solution. Any recommendations or ways of makign fsolve resolve arbitrarily close solutions?

Thanks,
