With numeric optimization (for all functions) it works much faster.

Fourier-Fejer-Lanczos interesting too.
IrfanView "ResizeResample" zoom up/down in two options
Fourier or Lanczos the best.

Hi Ber. Nice technique, easy to implement. You can also make that as a function, and monocolor too.
Parametrisation.sm (25.37 KiB) downloaded 592 time(s).
Another option could be use y0 as vector, and solve for each element in y0, obtaining res, res1, ..., resn
Best regards.

1. SS 6179 does not complain
2. Takes ~ 1 hr to terminate the first function
3. NO plot result [NO complain but NO plot ?]
4. Would be interesting checking if the attached SS 6179
runs in your actual AlgLib 3.1x. If NOT => would be a dramatic bug.
It would indicate that all maths based al_nleqsolve would be scrap.

Plugin updated.
Changes:
- solution restructured;
- converting the task for the ODE solver to the numerical form is now performed through the Mathcad Toolbox plugin (to avoid code duplication), so it must be installed;
- refactored.
Solvers that support mathematical notation now reuse code from the Mathcad Toolbox plugin. Now there is no need to recompile every such plugin.
