Please see the attached file. It is a time series plotted from a very long row vector (1x10000), and I want to locate the position (red point) where a "large" fluctuation occurs. Any MATLAB function or simple way to do it? Thanks.

If you know the "time zone" where you have this minimum, just use min on this interval.
something like :
[Value,Index] = min(YourTimeSeriesValues(2500:4500));
