julian_day

Convert depth (in meters) to pressure in Pascals.


n = julian_day(y,m,d) % Matlab & Octave
n <- julian_day(y, m, d) # R

Convert between dates and Julian day numbers. n = julian_day Returns the Julian day number for today. n = julian_day(y,d) where y is a single year or a vector of years and d is a single day number or a vector of day numbers Returns the date vector [year,month,day] for each year/day pair. n = julian_day(y,m,d) where y is a single year or a vector of years, m is a single month or vector of months, and d is a single month day or a vector of month days Returns the Julian day number for each year, month, day.

Input var Description Default value
y years N/A
m monthsN/A
d days N/A
Output var Description Units
n See Description for possible outputs for n N/A

Matlab & Octave

julian_day(2016,10,12) 
n = 286 
julian_day(2016,286)
n = [2016,10,12]

R

julian_day(2016, 10, 12) 
n = 286 
julian_day(2016, 286)
n = "2016-10-12"
