Hey Guys

I`m looking for a maplet that shuts down the entire program. A maplet that interrups the following steps and goes back to the beginning of the program.

Thanks for answers

Hy, 

I'm trying to display a list value in a maplet. But I can only manage to get textboxes, checkboxes and textfields. I know that in textfields I can display the evaluation of a function, but I tried many different ways and I still don't get the desired result. 

I designed a maplet with a button and 6 rows with a checkbox at the end of each row. When clicking the button I would like that the values of a list ("lstx", 6 values) are displayed in the 6 rows. Can you help me? thanx!!

I am dealing with Fourier series, I have series of sin(nw) + cos (nw) for different  value of n . How can I put all sin together and all cos together equal to zero, when n=1000 for example.

I created a Maplet that calculates ODE (Ordinary Differential Equations) however I would like to create a button that can allow printing on paper

I am using an old package, Janet, I got from http://wwwb.math.rwth-aachen.de/Janet/janet.html with Maple 16.

I changed the libname to point to the directory where the package files are.

Few days ago I was able to call help(Janet); without any problems but now everytime I try to call help(Janet)

Maple front-end loses connection to the ihe Maple kernel.

The package loads fine...

Dear All,

I am trying to call the maple function fsolve in the matlab. I have used maple('fsolve(x^2-4)'). It worked.

Now in the matlab code I have defined another variable. let us say a = 10.  Now I am trying to call the fsolve as follows.

maple('fsolve(a*x^2-4)')

I ended up with the following error.

Error, (in fsolve) number of equations, 1, does not match number of variables, 2

Hi...

I need to solve the pde 

eq := diff(diff(V(y, t), y, y)-alpha^2*V(y, t), t) = -I*alpha*U(y)*(diff(V(y, t), y, y)-alpha^2*V(y, t))-I*alpha*(diff(U(y), y, y))*V(y, t)-(diff(V(y, t), y, y))+alpha^2*V(y, t)

with U(y) as a known function

and boundary conditions as

bcs := {V(-1, t) = 0, V(1, t) = 0, (D[1](V))(-1, t) = 0, (D[1](V))(1, t) = 0}

and initial condition as

V(y,0)=phi(y);

both of phi(y) and U(y) can...

Hi,

     Theres seems to be an error in the SphericalY function when the input is SphericalY( l, -l, theta, phi)

restart;

Hi,

I'm trying to solve a pretty complex system of equations (a 3rd order DAE with 61 equations) using the MEBDFI numeric solver but I'm always getting the following error.

error in dsolve/dae/numeric/sm_intersect. numeric exception, division by zero

I have tried to find out what the sm_interesect command is but I haven't had luck neither in Internet nor in Maple help. I have looked for similar posts...
