Hi there,

I have a matrix that contains 1 years worth of data (where the elements correspond to date x time) ranging from the 1st January to 31st December; each row represents 1 day of data. Is anyone aware of a method to average each column over each month? Any help would be appreciated.

Thanks

Luke

I suggest using Sean de Wolski's answer with datetime and retime

Thanks. I have seen this before but could not get it working. I believe it is because I am dealing with data directly, meaning that each data point in the matrix is representative of a date and time. Whereas, the example is clearly split into Year Month ... format.
