I have a column vector which shows time. I'm trying to find out the index using the find command. My input command was. >> s=find(time==0.1000); >> s

s =

   Empty matrix: 0-by-1
The vector contains three values of 0.1000.I want the index of the last value. But it shows the above error message.

The index of the last element of "time" or of any 1-D array is "end" or length(time).
