在 MATLAB 中嵌套 switch 语句是可能的,可以在 switch 一部分外嵌套 switch 语句序列。即使 case 常量的内部和外部的 switch 含有共同的值,也不算冲突出现。
嵌套switch语句的语法如下:
switch(ch1)
case 'A'
fprintf('This A is part of outer switch');
switch(ch2)
case 'A'
fprintf('This A is part of inner switch' );
case 'B'
fprintf('This B is part of inner switch' );
end
case 'B'
fprintf('This B is part of outer switch' );
end
在MATLAB中建立一个脚本文件,并输入下面的代码:
a = 100;
b = 200;
switch(a)
case 100
fprintf('This is part of outer switch %d
', a );
switch(b)
case 200
fprintf('This is part of inner switch %d
', b );
end
end
fprintf('Exact value of a is : %d
', a );
fprintf('Exact value of b is : %d
', b );
当运行该文件时,它会显示:
This is part of outer switch 100
This is part of inner switch 200
Exact value of a is : 100
Exact value of b is : 200
