Determine in what interval a variable is

I have a vector with timestamps for different phases, for example

ElapsedTime = [0.13 0.35 0.74 1.02 1.39 1.80 2.50];

Where the first phase is between time 0 and 0.13, the second phase is between 0.13 and 0.35 and so on.

The length and values of the vector are dynamic and changes from time to time.

How can I determine to which phase a specific time value belongs to?

t = 0:0.01:ElapsedTime(end);

Use discretize.

ElapsedTime = [0.13 0.35 0.74 1.02 1.39 1.80 2.50];

t = 0:0.01:ElapsedTime(end);

phases = discretize(t, [0,ElapsedTime])

phases = 1×251

1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2
