Answer to Question #303961 in MatLAB for MR Z

Question

Plot on the same figure the calculated acceleration and the classification variable ds mapping

against time. Use left side y-axis and a line style to plot the acceleration. Use right side

y-axis to illustrate the driving style classification. Hint: You may use plotyy to complete this

task. Add labels to all axes. Add legend to the figure.

Driving Style: Normal, Acceleration = 0.70 m/s2

Driving Style: Economic, Acceleration = -2.30 m/s2

Driving Style: Economic, Acceleration = 2.31 m/s2

Driving Style: Economic, Acceleration = -3.30 m/s2

Driving Style: Economic, Acceleration = 3.31 m/s2

Driving Style: Agressive, Acceleration = -8.50 m/s2

Ds mapping

NORMAL = 2;

ECONOMIC = 5;

AGGRESSIVE=8;
