用matlab写一个GPS时间转UTC时间和日期

下面是一个简单的 MATLAB 代码示例，用于将 GPS 时间转换为 UTC 时间和日期：

function [utc_date, utc_time] = gps2utc(gps_week, gps_sec)

% GPS time origin is Jan 6, 1980 (UTC) 
gps_origin = datenum(1980,1,6,0,0,0);

% GPS seconds per week
gps_sec_per_week = 7*24*60*60;

% Compute the number of weeks and seconds since GPS time origin
gps_weeks = floor(gps_sec/gps_sec_per_week);
gps_seconds = gps_sec - gps_weeks*gps_sec_per_week;

% Compute the UTC time and date
gps_days = gps_seconds/86400;
[~, utc_time] = strtok(datestr(gps_origin+gps_week*7+gps_days), ' ');
utc_time = utc_time(2:end);
utc_date = datestr(gps_origin+gps_week*7+gps_days, 'yyyy-mm-dd');

end

该函数需要两个输入参数：GPS周数和自GPS时刻以来的秒数。输出是UTC时间和日期，以字符串形式返回。请注意，该函数仅适用于GPS时间和UTC时间之间的简单转换，而不考虑任何可能的误差或时钟跳跃。
