MATLAB: Loading a mat file using its location, without knowing its name

.mat fileload

I have a large group of mat-files with random names, in a specific folder. I want to load them in a for loop, sequentially.

Is it possible to load them without entering all of file-names in my code?

I really appreciate any help you can provide.

How can I process a sequence of files? Second method there'd work for you.

A smiple modification gives you the answer:

myFolder = 'C:\users\leon\documents'; % or whatever.
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
filePattern = fullfile(myFolder, '*.mat');
matFiles = dir(filePattern);
for k = 1:length(matFiles)
  baseFileName = matFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  storedStructure = load(fullFileName);
  % Now do whatever you need to do with the structure you recalled.
end

MATLAB: Loading files with a particular string on its name

See the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

% Specify the folder where the files live.
myFolder = pwd; % or 'C:\Users\yourUserName\Documents\My Pictures' or whatever...
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, 'Result*.mat'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
  baseFileName = theFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  % Now do whatever you want with this file name,
  % such as reading it in as an image array with imread()
  thisStructure = load(fullFileName)
end
msgbox('Done');
