I have a amplitude value with time period of a signal. I am trying to fit this signal by polynomial fitting. I have attached the amplitude vaueand written the code but it is not fitting. Is it possible to it using higher order of polynomial. I want to fit the curve using higher polynomial order (i.e. greater than 9) but it is not done. Please help me to solve this,
filename = 'value.xlsx';
A = xlsread(filename);

I recommend you use cftool to explore the fits.
