Fit a polynomial to data and plot it density_water.dat density_air.dat Step 1: write code to read the density-vs-temperature of both water and air data into two lists/arrays. (hint: for each row, you need to detect if first character is #, if so skip it, otherwise parse the data and save it to lists below). Water_temp=[] water_density=[] Air_temp=[] air_density=[] Step 2 Read the description below to generate a polynomial function that fit the data. Step 3: plot the results of the raw data and the fit polynomial function (hint: after you create the fit function in step 2, for each temperature value in water_temp or air_temp, calculate the value of density values and save to water_density_fit[] and air_density_fit[], and then you can plot them together).

MATLAB Code for question (2)
1) Use the Matlab function polyfit to curve fit the saturation pressure versus temperature data along the vaporization line for water in the table below with a polynomial of degree n. The Matlab function polyval may be used to evaluate the polynomial at any point. Compare the saturation pressure as calculated by the polynomial with the data given in the table and observe what happens as the degree of the polynomial n is increased. Tabulate...
