MATLAB: How to get absolute value

Question

I have some error data with time. and i want to get minimum absolute value from one time point till end time point.

for example

time 0 1 2 3 4 5 6

data 0.3 0.4 0.5 0.6 0.8 0.9 1.0

in the above example i want to get minimum absolute value from time = 3 to time = 6

so should i get this ?

right now i am doing like this

y = min(abs(e(3,end)))

e is variable where i am saving this time and data

Answer 1

time = [0 1 2 3 4 5 6]:
data = [0.3 0.4 0.5 0.6 0.8 0.9 1.0];
ini = find(time == 3);
fin = find(time == 6);
result = min(abs(data(ini:fin)));
