If the string S does not represent a valid number or matrix, STR2NUM(S) returns the empty matrix. [X,OK]=STR2NUM(S) will return OK=0 if the conversion failed. CAUTION: STR2NUM uses EVAL to convert the input argument, so side effects can occur if the string contains calls to functions....

When you simulate a model that contains aMATLAB Functionblock, the software generates binary code or C/C++ MATLAB executable (MEX) code from the block and integrates this code with the model. TheMATLAB Functionblock uses the same infrastructure asMATLAB Coder, which you use to generate C/C++ ...
