Please write a MATLAB program for polynomial fitting, the row data are given with the excel file.


MATLAB Programming Work 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:   2 11 2 3 ... n np x p p x p x p x      An equation with an order of 20 is preferred, where n = 20. 3. Next, use the extracted equation to output row data with the -5.00E-01 0.00E+00 5.00E-01 1.00E+00 1.50E+00 0 5 10 15 20 25 ID (A /m m ) VD(V) following:   0 ~ 20, 0.1x step y p x    4. Please set for auto generate an excel file for the output data
