Hi i have two non-linear curves one is from file and the other will be fit on first one and have 6unknown parameters. the equation is (R-1i*w)=sqrt(1+(2.41./(1-(0.389e-6./lada).^2))+(0.3./((1-(0.406e-6./lada).^2)+((1i.*0.06).*(0.406e-6./lada))))); lada=0.2e-6 to 2.5e-6 parameters 2.41, 0.389,0.3,0.406,0.06 and 0,406 will be changed in the equation. how can i find the right parameters of the original curve or fitting the graph to the original.
