Loading .mat files with same variable name
显示 更早的评论
I could do with some help.
I have loads of .mat structure arrays that contain 'data' (84x179). I want to be able to plot the data on top of each other but the problem is that since they are all called 'data', they replace each other in my workspace. What is a good way around this? Is there a way I can change 'data' for each .mat file or should I create a for loop. I don't know how to do this so any tips would be most appreciated.
Thanks

Hi,
the main idea is to use load with a return argument instead of as a command, something like
files = dir('*.mat');
allData = cell(size(files));
for ii=1:length(files)
aFileData = load(files(ii).name);
allData{ii} = aFileData.data;
end

Yes, that would be no problem. If you know that it's only one variable, use fieldnames:
aFileData = load(files(ii).name);
% names of the variables stored:
variableNames = fieldnames(aFileData);
% use the first name and "dynamic field names", i.e., (...):
allData{ii} = aFileData.(variableNames{1});
