Task: Write a MATLAB program for polynomial fitting
Item: Excel file with the x and y data include
Step:
1. Import the excel file with row-data, where row A for X-axis
and row B for Y-axis
2. Use MATLAB functions to extract the polynomial function of
the curve
Figure to plot:
Equation to extract:
  XXXXXXXXXX ...
n
np x p p x p x p x
    
An equation with an order of 20 is prefe
ed, where n = 20.
3. Next, use the extracted equation to output row data with the

6. Next, use the extracted equation to output row data with the
following:
 
 
 
