Updated 16 Dec 2023

This is a MATLAB function to obtain the GPS week, as well as the number of seconds that have elapsed from the start of the GPS week for any given sets of date/time.
The function returns the GPS week numbers (weeks) and the numbers of seconds that has elapsed since the start of the GPS week (secs) for a given set of date vectors (dv)
dv can be a vector or matrix in which the columns correspond to the form [year month day_of_month] or [year month day_of_month hour minute sec] in universal time UT. Example: for 31 March 2023, dv is [2023 3 31] at the UT start of the day, and [2023 3 31 15 36 0] at 15:36:00 UT of the same day.
The syntax is:
[weeks, secs] = gpsweek(dv)
For example, to get the GPS week for 31 March 2023: [weeks, secs] = gpsweek([2023 3 31]) which gives: weeks = 2255 as the GPS week, and secs = 432000 as the number of seconds that has elapsed since the start of the gps week
[week, secs] = gpsweek([2023 3 31 15 36 0]) gives:
week = 2255 as the GPS week, and secs = 488160 as the number of seconds that has elapsed since the start of the gps week
NOTE: THIS FUNCTION CAN BE USED WITH MULTIPLE DATE VECTORS SUPPLIED AT ONCE, AS A MATRIX RETAINING THE SAME NUMBER OF INPUT COLUMNS
