Question

Hello. I need help on part c of this problem.

We are using matlab and are expected to use the find function.

For instance, for part b,

I wrote something like

heightA= find(h>=15 & v<=36);

heightA_start=t(heightA(1));

heightA_end=t(heightA(end));

fprintf('The times when height >=15 and speed<=36 are from %6.2f to %6.2f', heightA_start, heightA_end);

For part c though, the times are from in two blocks like 0 sec to 1 sec and 3 sec to 5sec (Just made them up.)

How do I code for this??

Thank you
