I have a 3D matrix having dimension m*n*365 (where m & n represents the the number lat & lon grids;365 represents the daily rainfall data stored in each grids). How can I find the percentile value of rainfall data stored in 150th day for each grid?

Let A be your m*n*365 3D matrix. Extract 150th matrix out of it.

B = A(:,:,150) ; 

YOu can carry on your computation on B.

In that way, I can calculate the desired percentile value (say, 90th percentile) based on 150 days. But, I want to find the percentile value of data position in 150th day based on 365 days.
