Hi Can you advise how I can generate curve fitting coefficients using a curve fitting relationship: E=A*(X-B)^C+D for known X and Y (E=lnY), so I am looking for A,B,C,D of relationship: Y=EXP(A*(X-B)^C+D) for known X,Y. Can I use Curve Fitting ToolBox ?

x = lsqcurvefit(fun,x0,xdata,ydata) % in Optimization Toolbox
or
x = fminsearch(fun,x0) % in MATLAB
may help you to solve Y = EXP(A*(X-B)^C+D)
