My example: I needed to interpolate 1-D scattered data to obtain the wind speeds for the standard return periods. First, I found the needed parameters for my extreme data through dividing the extreme winds into different synoptic mechanisms and estimating the Gumbel variates for each. Second, I used them to calculate a vector of return periods T for a vector of wind speeds ws=5:0.1:50 (T is inverse of sum of probabilities). Third, I depict the wind speed for the standard return periods of 25, 50, 100, 500 years. Here is my simplest way for this third step: input - x is a vector of return periods for ws, y is ws, X is a vector of the standard return periods, Y is output WS corresponding to Y. Usable with any Matlab version.
