I wanted to define variables within a Matlab function in Simulink. To decide which values the variabels will have in the current simulation step the variable values from the previous simulation step are necessary and feedback delayed with a memory block.
If I do this I get an error message during compilation.
Without the feedback the model compiles but does not deliver the desired result.
I found the answer. Inside the Matlab function I was using various IF ELSE Statements. Not all output variables were set in each case leading to inconsistencies in the outputs. Nevertheless the failure message was really unclear about this fact.
