The semilogy function operates in an identical fashion to the plot function except that a logarithmic (base-10) scale is used for the y axis. Use this function to plot the data and function as described in Prob. 2.11. Explain the results. 2.13 Here are some wind tunnel data for force (F) versus velocity (ν):

Data From Problem 2.11

It is general practice in engineering and science that equations be plotted as lines and discrete data as symbols. Here are some data for concentration (c) versus time (t) for the photodegradation of aqueous bromine:

These data can be described by the following function:

c = 4.84e^−0.034t
Use MATLAB to create a plot displaying both the data (using diamond-shaped, filled-red symbols) and the function (using a green, dashed line). Plot the function for t = 0 to 70 min.

Example 2.13

These data can be described by the following function:

F = 0.2741ν^1.9842
Use MATLAB to create a plot displaying both the data (using circular magenta symbols) and the function (using a black dash-dotted line). Plot the function for ν = 0 to 100 m/s and label the plot’s axes.
