| I'm not sure when it's improved, but at least since _v12.3.1_, we no longer needs to split into triangle!: area[pts_] := Area[Polygon[pts], Assumptions -> {0 0} (* {28} *) |
| Neil Singer gave you good advice in checking out the fit. It just turned out that an even smaller value of `diffusion` is needed. nMax = 5; L = 0.05484; nlm = NonlinearModelFit[data1, 2 Sqrt[diffusion]*x*(1/L)*(Pi^(-0.5) + ... |
| Thank you kindly for each answer. It's an honour to be a member of such a wonderful community! MK |
| Hello, Thanks for your reply. You solution is a good idea. |
| Hi Reza Very strange usage of Do[ ] and Ne[ ], look at Neils post that's the right way. Keep the definition of Ne[ ] outside of any Do[ ] and Table[ ]. Alternatively to Neils suggestion you could suppress the unwanted plot region by using this... |
| Until you debug it, you might also want to return something like 0 if the code does not compute an answer to avoid an error. |
| Thanks Neil. I think it is clear that even without GraphicsInformation I can draw the Graphics without PlotLabel into a variable g, get AbsoluteOptions[g, ImageSize], use that width to size the PlotLabel and draw the Graphics again including the... |
| Jairo, I do not know the inner workings for PIDTune, however, it appears to have difficulty with the derivative for a system with such a long time delay. If you use a PI controller with some options, you get a reasonable response. For example, ... |
| oops, Sorry I forgot the Exp[] in the expression above. It evidently can't be integrated in closed form using existing techniques known to Mathematica. I tried Rubi and that failed as well. Regards, Neil |
| All zeros is one solution. If you use FindRoot you can find two more fairly easily: In[23]:= g /. \[Gamma]1 -> 0 /. \[Delta]1 -> 0 /. \[Gamma]2 -> 0 Out[23]= {0., 0., 0.} In[24]:= FindRoot[ g == 0, {{\[Gamma]1,... |
