matlab - 使用特定文件名保存矩阵 matlab

Question

我正在尝试保存具有特定文件名的 2 列矩阵，但我不断生成相同的错误消息:

Error using save
Must be a string scalar or character vector

我的代码如下所示:

    CustomName = ['TheDataFrom','_', animalname, '-', animalnumber,'-',num2str(stimNumber), num2str(stimType), '.mat']); % the name I want the file to have, changes with different specimens
TheData(:,1) =  codes(index,1);
TheData(:,2) =  times(values,1)); %both of these vectors are the same length

save(CustomName, TheData);

我还尝试通过首先将 TheData 设为空矩阵，将“TheData”变量设为双向量，因此代码看起来像这样，带有额外的行:

 CustomName = ['TheDataFrom','_', animalname, '-', animalnumber,'-',num2str(stimNumber), num2str(stimType), '.mat']); % the name I want the file to have, changes with different specimens
TheData = zeros(length(index), 2) %make a matrix of the right number of rows and columns, comes out as class 'double'
TheData(:,1) =  codes(index,1); %put data into each column
TheData(:,2) =  times(values,1)); 

save(CustomName, TheData);

我只想用一个样本特定名称保存这个矩阵，我不知道为什么我正在做的事情不起作用。请帮忙!

谢谢

您需要指定要保存为字符向量的变量的名称，这意味着您不希望实际将变量本身作为 save 的参数传递。而是创建一个包含要存储的变量名称的字符向量:

save(Customname, 'TheData');
