Fourier-Fejer-Lanczos interesting too. IrfanView "ResizeResample" zoom up/down in two options Fourier or Lanczos the best. Fourier Fejer Lanczos.sm (10kb) downloaded 49 time(s).

Hi Ber. Nice technique, easy to implement. You can also make that as a function, and monocolor too. Parametrisation.sm (26kb) downloaded 55 time(s).Another option could be use y0 as vector, and solve for each element in y0, obtaining res, res1, ..., resn Best regards. Alvaro.

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. Contour SOLVE [Electron Solve algo Express].sm (21kb) downloaded 56 time(s).

Plugin updated. Changes: - al_lspline(), al_pspline() fucntions added; - some functions now have a reduced number of parameters (input vector lengths are no longer required); - refactored. |

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. |
