Allow calls to extrinsic functions.

An extrinsic function is a function on the MATLAB path that MATLAB Coder dispatches to MATLAB software for execution. MATLAB Coder does not compile or generate code for extrinsic functions.

When enabled (Yes), generates code for the call to a MATLAB function, but does not generate the function's internal code.

When disabled (No), ignores the extrinsic function. Does not generate code for the call to the MATLAB function — as long as the extrinsic function does not affect the output of the generated code. Otherwise, issues a compilation error.

Disabling this option results in faster MEX function execution.

You should not disable this option if your MEX function relies on extrinsic calls.
