matlab identify position of min and max

Question

I have a time series and have calculated the min, max and mean values. However, I want to know at which year the min and max observations occurred. How is it possible to identify the ith position of the min and max values in the dataset?

Answer 1

You find it using find command.

for example:

M = [1992, 3 ,5; 1997, 8 ,2; 2000, 2, 15]
[~,min_i] = min(M(:,2)) %return the row index of min vaule in the 2nd column.
year_of_min = M(min_i,1)
