Datetime arithmetic in simulink
显示 更早的评论
Hello, is it possible to do datetime arithmetic in simulink? Eventually, the code may be autogenerated to C++.
for example, in matlab i would do:
dt0 = datetime([year month day hour min sec])
increment = 0.5 % seconds
dt1 = dt + seconds(increment);

You can do some arithmetics with datetime data type. For your example it is possible to add a duration to a datetime.
dt0 = datetime([2023 8 25 11 47 3]) % a point in time
increment = duration(0,0,5) % a duration of 5 seconds
dt1 = dt0 + increment % a 5 seconds later point in time

In general a Simulink block is generating a signal (in case of of a source block) or manipulating a signal using block parameters or other signals. datetime or duration are no valid data types for signals. Or what is your intention to deal with those data types in Simulink?

I am not familar with the Aerospace Blockset but according to documentation the Julian date conversion block supports only data type double on its inputs and its outputs. I don't see the nessity or possibility to deal with data type datetime or duration. But maybe it is possible to write a function within a MATLAB Function block with double inputs and double outputs where you convert those doubles into datetime and/or duration and convert the results back to doubles. But I am not sure if that is what you want
