Warnings for Non-existent Ports in a Matlab Function Block
1 view (last 30 days)
I have a rather large model in Simulink. When it runs, it gives me a number of warnings similar to the following one:
Warning: Block 'SS_SplitSimulink_Model1/MATLAB I1/ SFunction ' output 'Inf'
for element 23 of output port 2 at minor time step 0.00016552
The strange thing is that the "MATLAB I1" block has only one output port. Is there any way in which a Matlab function block can have something like hidden ports? I get 'Inf" and "NaN" warnings, which is obviously quite troubling...
I apologise if I'm not giving enough info.
