Switch Block has two possible outcomes: input 1 or input 3. The cyclomatic complexity of the block should have been 1 according to its defination in the documentation .
Why does the Simulink check API (slmetrics) return 2 instead of 1. Am i missing something ?

A Switch block is an equivilant of an if-else statement. Its cyclomatic complexity number is 2.

Good point! Contact the Mathworks tech support and ask to explain the cases of a Switch block and a multi-port Switch block, i.e. what is N and "On". It seems the documetation has error.
