Hi, I am trying to generate a speed range in MATLAB. Let second by second vehicle speed data samples is V (km/h) = 0 13 27 38 54 70 84 93 102 98 66 37 25 9 0 22 41 75 81 98 105 92 85 43 61 48 17 13 6 3 0. How to write the coding to classify the value of V based on speed range of:
0<V<=60
60<V<=80
80<V<=110
V>110

v1 = V((V>0) & (V<=60)); numV1 = numel(v1);
v2 = V((V>60) & (V<=80)); numV2 = numel(v2);
v3 = V((V>80) & (V<=110)); numV3 = numel(v3);
v4 = V(V>110); numV4 = numel(v4);

Use the histogram or histcounts functions, depending on whether or not you want a graphical representation of the distribution of your values.
