The most commonly used trick is to create a subfunction that will check whether we are running octave, and use it as condition to run selected block of code that are incompatible. Due to the persistent variable it can be called repeatedly without a heavy performance hit. | The most commonly used trick is to create a subfunction that will check whether we are running octave, and use it as condition to run selected block of code that are incompatible.
