How to do the following on MATLAB

Repeat the practice problem P 12-2 for the following motion: Time(sec) 0 0.5 0.5 1.0 1.5 01 20 20 55 55 34 02 -20 -20 10 10 -29 45 Determine the joint motion trajectories for 01 and 02 using the cubic spline method for time varying from 0 to 1.5 sec with an increment of 0.01 s. For your plots of 01 and 02, use markers of your choice only for the data points in the table. Use solid lines for the interpolated data points. Please see P 12-2 practice problem. Make sure to add appropriate axes titles (Time(sec)-th_1 and 2 (deg)) and legends.
