It would be helpful to know what system or application you are working with and what action you were trying to perform when you received this error message.

抱歉，MATLAB 中没有直接对应的容器类型来实现字典。您可以使用结构体来替代字典的功能。请尝试以下代码：

value = {};

for i = 1:length(floders)
floder = floders{i};
disp(floder);

imgname = strsplit(floder, '_');
imgname = imgname{1};
idx = tinydict.(imgname);
value{end+1} = idx;
value{end+1} = floder;
sum = 0;

imgs = dir(fullfile(floderPath, floder));
for j = 1:length(imgs)
img = imgs(j).name;
brisq.get_feature(fullfile(floderPath, floder, img));
score = brisq.get_score(fullfile(floderPath, floder, img));
disp(score);
sum = sum + score;
end

value{end+1} = sum/frames;
disp(sum/frames);

s = struct(value, df.columns);
df = [df; s];
value = {};
end

writetable(df, outpath);

这个错误通常是由于在MySQL数据库中指定的用户 'root'@'%' 不存在导致的。要解决这个问题，你可以尝试以下几个步骤：

1. 确认用户是否存在：使用管理员权限登录到MySQL数据库，并执行以下查询来检查用户是否存在：

   SELECT User FROM mysql.user WHERE User = 'root' AND Host = '%';

如果查询结果为空，则表示用户 'root'@'%' 不存在。

2. 创建用户：如果用户不存在，你可以尝试创建一个具有相应权限的用户。执行以下查询来创建一个名为 'root'@'%' 的用户，并授予所有权限：

   CREATE USER 'root'@'%' IDENTIFIED BY 'your_password';
   GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
   FLUSH PRIVILEGES;

请确保将 'your_password' 替换为你想要设置的密码。

3. 重新连接数据库：完成上述步骤后，尝试重新连接数据库并执行你的操作。

如果上述步骤无法解决问题，请提供更多的错误信息和操作细节，以便我能够提供更准确的帮助。
