I am trying to understand how to convert ordered vector into a matrix. Here is my problem:
The correspoding values are identified by their position in the vector. This is to say that at the location lat(1)=4 e lon(1)=32 there was a wind speed of wind_speed(1)=12.
What I would like to have is two vector of lat and lon with unique and ordered values and a 2D matrix of wind values. My aim is to plot it with the function contour as
where X and Y are the new vector of ordered and unique lon and lat values and win_spd is a matrix with the the dimesion of X by Y.
Any help is greatly appricieted!
