MATLAB program that computes the average thrust, total impulse thrust, and determines maximum thrust and time of maximum thrust.  As mentioned above, the first column of numbers in the EML600 two-dimensional matrix is time and the second column of numbers is thrust.  The total impulse is calculated by integrating the thrust values over the entire time the motor is firing.  Basically you are computing the area under the thrust curve.  The equation is:                           total_impulse = total_impulse + (thrust1 + thrust2)/2 * (time2 - time1)   Print the results as shown below to the Command Window only.  Develop a plot of time and thrust similar to the graph shown above. Add a title, x and y labels, show the grid, set the axis square, and set the tick marks.
