输入一个字符,若为大写字母,则输出其对应的小写字母;若为小写字母,则输出其对应的大写字母;若为数字字符,则输出其对应的数值;若为其他字符,则原样输出。 输入输出示例:请输人一个字符D d 请输入一个字符d D 请输入一个字符11 请输入一个字符## 。用MATLAB选择语句

在MATLAB中,你可以使用`switch-case`语句来实现这个功能。下面是一个简单的示例代码:
```matlab
% 定义输入函数
function output = processChar(inputChar)
switch lower(inputChar) % 将输入转为小写以便比较
case 'a'..'z' % 大写字母转小写
output = char(uint8(inputChar + 32));
case 'a'..'z'.'A'..'Z' % 小写字母转大写
output = upper(inputChar);
case '0'..'9' % 数字字符保持不变,转换为数值输出
output = num2str(double(inputChar));
otherwise % 其他字符原样输出
output = inputChar;
end
end
% 测试例子
inputExample = {'D', 'd', '11', '##'};
for i = 1:length(inputExample)
disp(['请输入一个字符: ', inputExample{i}])
result = processChar(inputExample{i});
disp(['输出结果: ', result])
end
```
运行此程序会依次处理每个输入字符,并按规则输出相应的结果。
