just need help with the code part

Problem 1: 1. Locate the MS Excel file ENGR25 HW3 Prob1 AreaData.xlsx on Canvas 2. Download the spreadsheet file onto your MATLAB-capable computer 3. Import the spreadsheet file into MATLAB using the xlsread command 4. Use MATLAB to calculate the mean, or average, value for each column Problem 2: 1. Locate the "Comma Separated Value" file ENGR25 HW3 Prob2 ScopeMeter.csv on Canvas 2. Download the file onto your MATLAB-capable computer 3. Import the data into MATLAB Each Column contains 255 data values o The Data Column Identification Column 1 Time in seconds . Column 2 Electrical Potential (lo) in volts . Column 3 Electrical Potential (hi) in volts 4. Take the mean of the corresponding Column 2 and Column 3 row-values to create a column-vector of average potentials that correspond to each time data-value. 5. Create a plot of the average potential vs time. Properly label and title the plot. Problem 3: 1. Locate the .txt file ENGR25 HW3 Prob3 Raman.txt on Canvas 2. Download the file onto your MATLAB-capable computer 3. Import the data into MATLAB 1. Column 1 Wave number in wavelengths per centimeter 2. Column 2 Raman Spectroscopic Intensity in arbitrary units (A.U.) 4. Create a plot of the Raman Intensity vs Wave Number. Properly label and title the plot. Problem 4: o 1. Locate the xlsx file ENGR25 HW3 Prob4 TvsX.xlsx on Canvas 2. Import the Data into MATLAB using the Import Tool You may view walk-through video here o Column B Distance in inches o Column C Temperature in C 3. Calculate the spatial gradient (spatial derivative) using the MATLAB code fragment shown below diffT = diff(TempTC); diffx = diff(Distancexin); dTdx = diffT./diffx; plot(Distancexin(2:573),dTdx, 'LineWidth, 2) 4. Create a plot of dT/dx vs x. Properly label and title the plot. Problem 1: 1. Locate the MS Excel file ENGR25 HW3 Prob1 AreaData.xlsx on Canvas 2.
