I was wondering if there's a simple way to add something like an interpolation loop to a procedure. For example, say I have a function of 2 vars which is expensive to compute, f(x,y). I can use option cache to speed up points which are already computed, but is there an easy way to interpolate between them using ArrayInterpolation? That is, if f varies on scales of order 1, if I have calculated it at 0.1, 0.2, then It can be guessed with a spline at 0.15 accurately enough. What...

I have the following procedure that generates Sierpinski's triangle:

seirpinski := proc (n)
> local Mat, Vector1, Vector2, Vector3,
> Prob1, Prob2, Q, prob, counter, fractalplot;
> Mat := linalg[matrix]([[.5, 0.], [0., .5]]);
> Vector1 := linalg[vector]([0, 0]);
> Vector2 := linalg[vector]([0, 0.5]);
> Vector3 := linalg[vector]([0.5, 0]);
> Prob1 := .333; Prob2 := .333;
> Q := linalg[vector]([0, 0]);
> writedata("fractaldata", [[Q[1...

I guess someone is kidding with me...

I want unsubscribing of this s... place!

I have this non-linear ODE in q(p):

ode := diff(q(p), p) = (q(p)-a*p)/(p-a*q(p))*(p^(-b)-1)/q(p)^(-b);

for some real parameters a and b, it may be solved in exact form for the special value a=1.

Is there any hope of getting a closed-form solution or of expressing the solution in a neat way for the case 0<a<1? even some specific value of a would be of interest, e.g. a=1/2.

dsolve(eval(ode,{a=1}));

let us consider the series

y = a_0 - sum(a_i,i=1..n)

here the terms a_i are defined recurrsively as follows

a_i = (a_(i-1) -4*ln(x)/ln(10) + 4/10 + 4*ln(a_(i-1)) )/ ( 1+ 4/(a_(i-1) * ln(10)))

how can i program this in maple. so i can...

what is the general sum formula for the following seires (we may notice from these few terms it has a pattern)

f:=x->x^3:
y[1]:=0.5:
y[3]:=subs(x=y[1],f(x)):
i := 2:
y[i] := y[i-1]-(y[1]-y[2+1])*(1/2):
i:=1:
g[i] := (y[i+1]-y[i+2])*x/(y[i]-y[i+1])+(y[i+2]*y[i]-y[i+1]*y[i+1])/(y[i]-y[i+1]):
g[i] := unapply(g[i], x):
h[i] := unapply(solve(y = g[i](x), x), y):
for i from 2 by 1 to 7 do
g[i]:=(f@h[i-1])(x);
g[i]:=unapply(g[i],x);
y[i+2]:=subs(x=y[i+1],g[i](x));
s:=solve(z=g[i](x),x);
h[i]:=unapply(s[1],z);
end do:

for i from -1 by -1 to -8 do

 Hello,

I am trying to use a worksheet developed by Professor Batista [ritz06.mws] for calculating plate vibration frequencies using the Ritz method, which is available from the Applications directory - Mechanical Engineering folder.  The worksheet was developed using Maple 12 and I am using Maple 11; a careful reading of the file didn't show any commands that were incompatible across the two versions and yet I am not able to solve the worksheet using the default inputs provided in the worksheet.  I have attached a PDF output of the file with the error message.  Any assistance that could be offered would be greatly appreciated.

Please send your response to wayne.bell@fpl.com.

Kind regards,

Friends,

I am very beginner of Maple softs, in order to proceed with my project i need to model a simple Human Knee joint and  to do its simulation, Somebody please help on this, otherwise i cant able to proceed with my project.

Waiting for a solution

Hey!

I'm really new on using maple 14 and I need help please.

I want to either connect maple 14 software with an oscilloscope for data acquisition or import the data captured by the oscilloscope to maple 14 and manipulate this data with the software for dynamic system analysis so I was wondering if anyone knows a programming code or a command to do this please =( I'm stuck

Thanks for your attention...

Hi,

I would like to define the following exceptions:

0/0 should be equal with 0, but any other x/0 should be infinity, if x>0 or -infinity, if x<0.

In the following example, I show what I achieved, however, I also would like to have equation (8) to be infinity.

Hello,

I have got a question. I have an Hamiltonianfunctionand want to differentiate this function to all variables. There is no problem with most of the variables, but one doesn't work. The error above occures, when I use the button "execute the entire worksheet". When I just press Enter, the errror does not occure and the right results are presented. But I am not abel to use the results.

Has anyone an idea how I can solve this problem?

Thanks in advance.
