(b) Plot the velocity distribution, and determine the shear stress at the wall. Hints: While there is no “one way” to do this in MATLAB, try fitting the discrete data with the POLYFIT command. I prefer to plot functions using the POLYVAL command, which constructs a set of discrete data from a function at specified intervals, and then, the PLOT command to plot these data. There are other ways too. Explore!...
