Dear Community,

I would like to have a 3D matrix, where each of the matrix elements is a collection of different kind of data, e.g. integers, real (float) numbers, logical variable, 1D vector of integers or reals, 1D vector of logical variables, etc. In other words I would like to store a collection of different data on a 3D grid. This collection is of course identical for all grid points, i.e. matrix elements. I experimented with DataFrames, but it did not allow me to use vectors. How could I realize such a structure in Maple? It is done quite easily in MATLAB e.g. with the "struct" command, or in FORTRAN with the "Type" command.

Many tx in advance,

best regards

Dear Community,

 

I tried to run a very simple dumped oscillator in MapleSim. Upon running however I do not get any result plots. Nothing appears in the result window :-/ Could you pls. have a short look at it?

Tx in advance,

best regards

Dear Community,

I try to solve the following very simple ODE symbolically with the ODE Analyzer assistant, yet Maple says "unble to obtain solution". :-/

If I try to slove it with dsolve, nothing happens. Is it really so difficult?

diff(p(h),h)=A/(B+C*p(h)), p(h0)=p1

A, B, C, h0 and p1 are constants. I use Maple 2016.

Tx in advance,

best egards

Dear Community,

Entering a long line in 1D mode breaks at the right window bounday. How could I prevent this? I would like the entered line stay just as one, single, long line extending over the window boundary and I would like to use the bottom window scroll bar to view it. BTW it also does not appear, so how could I invoke it? I use Maple2016. I have neither found any information about this in the help, nor in the documentation.

Also is there a possibility to split the IDE screen vertically, as e.g. in Visual Studio? Looking at long programs this feature is very useful.

tx in advance,

best regards

Dear Community,

Would someone have a good and easy to understand/implement description of the Den Iseger algorithm for the numerical inversion of Laplace transform? Even better if someone would have a Maple script to do it, that would be superb.

Tx in advance,

best regards
