It will be possible to manipulate this behavior with options "dsolve / event" or "dsolve / Error Control"?

Hola,
How can leave a trail/trace of black point in the yellow and purple screens? Something very similar to the option "animate / trace."

Make it possible to take the numerical data of each screen from the "plottools [getdata]"

Gracias

Hi,

How to avoid the following warning with the command NLPSolve / modifiednewton:
Warning, convergence is not assured; examine Hessian values, or consider raising tolerance

How to implement the following operation in Maple, as in MATLAB:

A(~isprime(A)) = 0

A =      0     3     2    13 
           5     0    11     0     
           0     0    ...

Interesting behavior!!
