Hi All,

Is using the NAG package the right way to go about creating the delaunay triangulation of a set of points in 3 dimensions. My points all lie on a surface in R^3.

Thanks. 

I have looked at the maple help for the ErrorPlot function, but i can't make it work for my plot. 

I have the following procedure:

K := 1.; Xrng := [seq(dt*i, i = 0 .. ntime)];

value := array(1 .. ntime+1);

ave := array(1 .. ntime+1);

for j to ntime+1 do:

discountfactor := exp(-r*j*dt);

Stot := 0.;

Stot1 := 0.;

for i to npath do:

Spath := max(Spot[i][j]-K, 0);

Stot := Stot+Spath;

When entering an expression into Maple that is not in simplest form ( Maple desktop will automatically change it to x+y. I have tried subtracting equivalent expressions, using evalb, using convert, and using simplify, but I cannot get 2*(x+y)/2 to be equivalent to (x+y) using the MapleNet web service.

Any help appreciated.

When I use pdsolve to solve a system of PDEs, and tell it to use HINT='*', does the solution I get ONLY contain those obtainable by separation of variables, or does it use separation of variables as a starting point and deliver the general solution? And how can I tell?

Hi,
I want to call Maplets from Flash, 

1.I have been using TA for some years but we have only recently moved from version 4 to version 6. In versions up to version 5, when a question was edited there was a two stage saving process ie. the question was saved and the question bank was saved. Only after these two saves did assignements containing the question reflect the edits in the question. I have an assignment which depends on a question in TA6 and I have edited saved the question. The assignment does not reflect...

Dear all,

I wrote some simple functions in Maple 13, called "myproc" file,

and used startup code (edit-->startup code) to initialize it in a worksheet by: read "myproc";

Now I am using Maple 14, it does not work, says, "unable to read", sort of thing.

I have also tried to rename the file to myproc.m and read "myproc.m";

does not work either.

Is there any compatibility problem?

Thanks.

Hi,
I want to call Maple from Excel, this works so far. Problems in the attached Excel sheet:

- The result of a Maple command (components of a vector) will not be placed into separate cells. How can this be done ?
- To auto-update the solution when changing the input matrix, for each component of the solution vector the complete matrix needs to be recalculated. Surely, there is a better way to do this. 

 Hi mates!

Can anybody tell me - is there in maple something like Paskal's begin and end for if-operator?

big thanks in advance)

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!

Please explain details of the fmt string in the mapleta function numfmt.  The help page only says

Returns the value of x, formatted according to the template fmt.

 For example,

 numfmt("#.00", 20.9)
