Question

Do some self-directed learning and provide an example of how to use the switch-case statement in Matlab.

Expert Solution
Step 1: Explanation
  • A switch block executes one set of statements based on one of several options. A case statement is used to cover each option.
  • A scalar or string is an evaluated switch expression.
  • A scalar, a string, or a cell array of scalars or strings is an evaluated case expression.
  • Each case is tested in the switch block until one of them is true.
  • When a case is true, MATLAB performs the statements associated with it before exiting the switch block.
  • The otherwise block is optional and only executes when none of the cases are true.

Syntax:

switch <switch_expression>

   case <case_expression>

      <statements>

   case <case_expression>

      <statements>

      ...

      ...

   otherwise

      <statements>
