I need to get the system date and time in my simulink model, which is used for XPC target. In simulink, this is not a problem, using the embedded matlab function with the following code:

function [Y, M, D, H, MN, S] = sysClock()
       coder.extrinsic('clock');
       Y = 0;
       M = 0;
       D = 0;
       H = 0;
       MN = 0;
       S = 0;
       [Y, M, D, H, MN, S] = clock;
   end

However, this block gives me error messages when I try to compile it to XPC. Is there another way? Or do I need to change the code? Shouldn't be such a difficult problem I would say...

Thanks!!

在 MATLAB Online 中打开

Thanks, but when I try to mex xpcwalltime.c, I receive the following error:

Error xpcwalltime.c: 122  type error in argument 3 to a function; found `int' expected `pointer to const struct DimsInfo_tag'

I use XPC target 5.1 FWIW

Where do you get xpcwalltime.c from? The file in the above solution is named xpctimeofday2.c, and I am able to compile it successfully with the mex command.
