Would LSQCURVEFIT work with comparing two complex functions? It looks like the metric for success is min sum {(FUN(X,XDATA)-YDATA).^2}, where it should be min sum {abs(FUN(X,XDATA)-YDATA).^2)} for complex-valued
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...
