Least Square Minimization (Levenberg-Marquant method) of damped oscillation curves
11 views (last 30 days)
My goal is to fit my experimental data (attached) with the following equation with Levenberg Marquant method :
A*exp(-c*t)*sin(2*pi*f*t+phi), where A is the amplitude, t is time, c is the damping coefficient and f the frequency and phi the phase coefficient.
As my skills are weak in least square minimzation in Matlab, thanks in advance for your help,
