a=30;
if a<20

end

 switch语句语法：

switch <switch_expression>
   case <case_expression>
     <statements>
   case <case_expression>
     <statements>
     ...
     ...
   otherwise
       <statements>
end

例如：

   case \'C\' 
      fprintf(\'Well done
\' );
   case \'D\'
      fprintf(\'You passed
\' );
   
   case \'F\' 
     fprintf(\'Better try again
\' );
     
   otherwise
     fprintf(\'Invalid grade
\' );
   end

结果：
