Switch case statement in Octave GNU

Octave is open-source, free available for many of the platforms. It is a high-level language. It comes up with a text interface along with an experimental graphical interface. It is also used for various Machine Learning algorithms for solving various numeric problems. You can say that it is similar to MATLAB but slower than MATLAB.

Switch case statements are a substitute for long if statements that compare a variable to several integral values. Switch case in Octave is a multiway branch statement. It allows a variable to be tested for equality against a list of values.

Switch statement follows the approach of mapping and searching over a list of values. If there is more than one match for a specific value, then the switch statement will return the first match found of the value matched with the expression.
