Answer to Question #303956 in MatLAB for MR Z

Question

Create variable ds mapping to store corresponding classification values of 1,2 or 3, which represent different driving style as shown in Table 1. You need to evaluate only the magnitude the of the acceleration/deceleration. If the acceleration value is outside the defined ranges assign 0 as its classification.

Table 1 (4 by 2)

Driving style Economic (1) Normal (2) Aggressive (3)

Acceleration magnitude [m/s2 ] 0.7-2.3 2.31-3.30 3.31-8.5 

Economic (1)

0.7-2.3

Normal (2)

2.31-3.30

Aggressive (3)

3.31-8.5
