Day of Year to MATLAB date

Converts a day of year number and a year to a date in MATLAB format

Description

DOY2DATE.m will convert a vector of day of year numbers and years
and convert them to MATLAB date format.
 
Sample Call:
 doyV = [54;200.4315];
 yearV = [2009;2009];
 [dateV] = doy2date(doyV,yearV);

Inputs:
 doyV -> vector of day of year numbers (n x 1)
 yearV -> vector of years (n x 1)

Outputs:
 dateV -> vector of MATLAB dates (n x 1)

function [dateV] = doy2date(doyV,yearV)
z = zeros(length(yearV),5);
dv = horzcat(yearV,z);
dateV = doyV + datenum(dv);

Your script was helpful in finding out the "key" 3 lines of code that did the job for me:
z = zeros(length(yearV),5);
dv = horzcat(yearV,z);
dateV = doyV + datenum(dv);
