![]() You need to input rough guesses for the fit parameters. NONLINEAR LEAST SQUARES THEORY to allow for smoother transitions of structures. ![]() This tutorial shows how to achieve a nonlinear least-squares data fit via Matlab scriptCheck out more Matlab tutorials: 1 An example of a (constrained) nonlinear least squares The basic structure of a (constrained) nonlinear least squares problem is the following The coefficients are estimated using iterative least squares estimation, with initial values specified by beta0. A = optimvar( 'A' ,2) r = optimvar( 'r' ,2) Create an expression for the objective function, which is the sum of squares to minimize. See Nonlinear Least Squares (Curve Fitting).
