SWITCH  SWITCH Switch statement


Usage
 
 The switch statement is used to selective execute code
 based on the value of either scalar value or a string.
 The general syntax for a switch statement is
 
   switch(expression)
     case test_expression_1
       statements
     case test_expression_2
       statements
     otherwise:
       statements
   end
 
 The otherwise clause is optional.  Note that each test
 expression can either be a scalar value, a string to test
 against (if the switch expression is a string), or a 
 cell-array of expressions to test against.  Note that
 unlike C switch statements, the FreeMat switch
 does not have fall-through, meaning that the statements
 associated with the first matching case are executed, and
 then the switch ends.  Also, if the switch expression
 matches multiple case expressions, only the first one
 is executed.
