Detect Inf or Nan in Embedded Matlab Function block

조회 수: 3(최근 30일)
Is there a way to detect an Inf or Nan being calculated inside an Embedded Matlab block. Simulink does not produce an error, but when we generated code, an exception was found. We are looking to protect against them. The problem can be reduced to the following.
[Constant block=0] --> [Embedded MATLAB Function] --> [Display]
Embedded MATLAB Function
function y = fcn(u)
test = 1/u;
if test > 0
y = 1;
else
y = 0;
end
"Configuration Parameters > Diagnostics > Data Validity > Inf or NaN block output", is just that, checking block output, and does not report this. (Which surprised me.)
Note: Simulink 6.6.1
Thanks.

Maybe there is a way to disable such error message in configuration parameters. I will check it.
