doy2md.pro

topdoy2md

time conversion

result = doy2md(doy, year)

convert a day of year to a month day

no restrictions that I know of, could probably get rid of recursive for loop for something better

Return value

[month, day], (1 = January, ..., 12 = December) (days from 1-31)

Parameters

doy in required: the day of year (is chopped to an int) may be an array
year in required: for Pete's sake use 4-digit an arry if dirrent years or can be a scalar for all
