| 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,... |
| It is the metaphor for the tool am creating to help other disabled folks use MMA well. A 11 yr long project. A curb cut is made so wheelchairs can get onto a sidewalk without struggling over a 3 inch curb. The cool Code Assist is good but has... |
| Lance, You should not be using strings to construct expressions in Mathematica except in unusual cases. In this case you can do what you want directly without any strings. I can't understand what you want the final output to look like unless you... |
| In my problem, System`TRootsDump`GuessRealRoots works 10 to 300 times slower than Ted Ersek's RootSearch. |
| Fantastic! It works now. Thank you very much Neil. Have a good weekend. Regards, Arasan |
