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 0 0.2 0.4 0.6 0.8 -8 -6 -4 -2 0 ID (A /m m ) VG(V) DG_VG2_-1 DG_VG2_-1 following:   4 ~ 0, 0.1x step y p x     4. Please set for auto generate an excel file for the output data 5. Please plot the three derivative equation.       1 2 3 ' '' '' g p x g p x g p x    6. Next, use the extracted equation to output row data with the following:       1 1 2 2 3 3 4 ~ 0, 0.1 ' '' '' x step y g p x y g p x y g p x         
