可以使用MATLAB中的`xlsread`和`xlswrite`函数来读取和写入Excel文件,同时使用`unique`函数来查找出现相同的中文字符,再使用`regexp`函数来进行替换。
以下是一个可能的解决方案:
```matlab
% 读取Excel文件
[~, ~, raw] = xlsread('example.xlsx');
% 将Excel文件转换为字符串格式
str = join(string(raw(:)), ',');
% 查找出现相同的中文字符
[unique_str, ~, idx] = unique(str);
counts = accumarray(idx, 1);
repeated_str = unique_str(counts > 1);
% 替换相同的中文字符并编号
for i = 1:length(repeated_str)
rep_str = repeated_str(i);
pattern = ['(', rep_str, ')+'];
idx = regexp(str, pattern);
for j = 1:length(idx)
if ~isempty(idx{j})
str{j} = regexprep(str{j}, pattern, [rep_str, num2str(j, '%03d')]);
end
end
end
% 将替换后的字符串写回Excel文件
output = reshape(str, size(raw));
xlswrite('output.xlsx', output);
```
此程序将读取名为`example.xlsx`的Excel文件,并查找出现相同的中文字符。对于每个重复的字符串,它将在字符串中使用正则表达式查找所有出现的实例,并用一个三位数字编号进行替换。最后,替换后的字符串将写回Excel文件,并保存为`output.xlsx`。
