Figure 7 below shows one cycle of a periodic wave, v(t) with an 8 second period. The first and last segments of the signal are straight lines with positive and negative slopes, respectively (you can derive their equations by examining the plot). The mid-segment is simply a straight line with a constant value. Write a MATLAB script that will prompt the user for the number of cycles to plot, and then plot them (e.g. the result for eight cycles should look like Figure 8). Use a sampling rate of 100 samples/sec. Submit your code.
