Lagrange Interpolating Polynomials using Matlab

Hello.,

Anybody here can help me to solve my I/O curve fitting using lagrange method. Here is below I attached several direction that I nedd to find. I also attached the script that I've do it before and my example curve fitting in PPT. Thank you

Best Regards,

You must use a fitting tool, not an interpolation tool to solve your problem.

Apply "polyfit" with x-values = Generation Output [MW] and y-values = Fuel Cost [NT$/kWh] and n = 3.

Hello,

Thanks for your respone. Would you give an example of the script in Matlab? I need to input the equation of curve fitting in the script that I show in the file also (attached before)?

Thank you
