WebMar 16, 2024 · I am fitting a function nonlinearly using the lsqnonlin function. I have used the [x, res] to return the parameters (i.e. x) and the residual (i.e. res). I am wondering if there is any way to return the best fit of the objective function instead of returning only the parameters and the residual. Web1. In fact, as long as your functional form is linear in the parameters, you can do a linear least squares fit. You could replace the ln x with any function, as long as all you care …
