question about formulating a nls optimization
...One problem that I identified is that the algorithm does not change the values of the parameters at all. It calculates the objective function OK, but the parameters are not updated. The function pdfDY is a Fourier integral with parameters xEx, tEx, gamma, theta, kappa, that I calculate with a Filon algorithm. The calculation of pdfDY is correct. Can anybody help me with this? Thank you very much, Adrian
