load a matlab file

Hi!

i have big data and i saved it in a mat file named All_data.

 %
save('All_data','data1','data2','data3')

            data1: [2970290x1 double]
            data2: [2970290x1 double]
             data3: {2970290x1 cell}

I want now to evalute the data in the file All_dat. Iused load('All_data'). But the data1, data2, data3 are not loadad.

should i load all of them with the load function, or there is any other smart method?

Thank you

Have you any error message when you type: load('All_data') ?

Try this

fullFileName = fullfile(pwd, 'All_data.mat');
if exist(fullFileName, 'file')
  storedStructure = load(fullFileName)
  data1 = storedStructure.data1
  data2 = storedStructure.data2
  data3 = storedStructure.data3
else
  warningMessage = sprintf('Error: the file does not exist:\n%s', fullFileName);
  uiwait(warndlg(warningMessage));
end
