MATLAB Answers How can I fit a complex valued function to my data? 1 Answer when running lsqcurvefit to fit the complex function: F = a1*exp(-1i*x*a2) + a3*exp(-1i*x*a4), i get a2 and a4 as complex estima... 4
Hi. I tried to fit simultaneous ODE using lsqcurvefit. Code works well and provide parameters. But parameters are coming as complex number. In my case parameters must be real number. How to restrict parameters to real numbers using lsqcurvefit?
What are the parameter value estimates that 'lsqcurvefit' returns? Are the complex parameter estimates conjugates? How well does the resulting function fit the data? 댓글을 달려면 로그인하십시오. 카테고리 Mathematics and OptimizationOptimization ToolboxNonlinear Optimization...

Hello Dear Matlab-Community, I am trying to do a Butterworth-Van Dyke (BVD) siumulation. I calculated my startparameters. Common X-values are between 1 and 3000. Common Y-values are between 1E-2 and 1E-4. I want to optimize 4 parameter (R_m, L_m, C_m, C_0) with TypicalX...

I'm sorry that I don't have an answer but I am also suffering from the same problem.
Open in MATLAB Online I haven't used lsqcurvefit myself, but if you want the real value of a complex number, you can use ThemeCopy a2 = real(a2); a4 = real(a4); 1 Comment joseph chahin on 15 Dec 2017 what I mean is...
