Who can help me solving the following problem with MAPLE?
Determing a square matrix M (if it exists) so that P = M^(-1)*J*M when square matrix P and diagonal
matrix J are given
Thanks

I'm trying to solve an equation with the aid of maple.
Maple responds with a "RootOf"-polynom of the fourth
order (a_4 z^4 + ... a_0).
I need the result/solution in a C program, so I would

I'm looking for solutions for following differential equation:
(2*diff(phi(theta),theta)^2 - phi(theta)*diff(phi(theta),theta,theta) +
phi(theta)^2) /
    (phi(theta)*(phi(theta)^2 + diff(phi(theta),theta)^2)^(3/2)) = Constant

The following procedure rotates a point p around an axis that contains
the points a1 and a2. The rotation angle is alpha.

Has anybody experience with operation of Maple 9.5 under Linux on an AMD Athlon
processor with 64-bit operating system, in particular Fedora Core (64 bit)?
Does the automatic installation work properly for you under these conditions?

This seems pretty straightforward to me:
a:=n->`if`(n=0,A,sum(a(i),i=0...n-1));
but for some reason it doesn't work (too many levels of recursion).
Can somebody give me a hint? TIA

Hi, Maple experts,
Is there a command to get 1)the vector of non-zero coefficients and 2) the
corresponding orders?  The case is the highest order of the polynomial is
really large, say, more than 100,000, so the vector is actually a sparse

Hi, all!
First of all, i am newbie in Mapple. I would like
to know  my plot causes this error. I have tried
w/ and wt/ the external "if". None of them worked.

I'm trying to solve a non-linear diff. equation using dsolve numerically and I
am getting an error message I don't understand.  Can anyone give me some
pointers?  Thanks.

some of my students asked me why Maple delivers this totally wrong
result. How does Maple show if there is no convergence in (f)solve?
This is with Maple 9.5.1

this is probably a very simple question, but I couldn't find an answer.
When I open a text file as Maple Text all lines a put into a single
execution group. Is it possible to split them to one command per
execution group without using 'split/join execution group' multiple times?

I have been looking for ways to determine certain model parameters by
fitting to measurement data. The problem is that all optimization techniques
need an actual function to work with. My initial equation which contains the
parameters to be determined (DD and Rdd) is so complex I ...

I am using version 9.03.
I tried
int(exp(-I*x^2),x=-infinity..infinity);
and received the correct answer: (1/2-1/2*I)*2^(1/2)*Pi^(1/2)

I would like to find the specific location of a certain value in my matrix
(min and/or max). I have very little experience with Maple, isn't there any
type of search function to go through lists or sets ?
greetings,

Hi, all!
How could i set up all my graphs at once, i.e.,
thick, font size, font type etc? May set to be
generated .eps graphs as well? Finally, how may i
