Try this robust approach:
baseFileName = 'kl.txt';
folder = pwd; % Or whatever folder you want.
fullFileName = fullfile(folder, baseFileName);
if exist(fullFileName, 'file')
  % File exists.  Read it into a structure.
  storedStructure = load(fullFileName);
  % Extract individual variables from the structure.
  a = storedStructure.a; % Or whatever the variable is called.

  b = storedStructure.b; % Or whatever the variable is called.
else
  % File does not exist.  Alert user
  warningMessage = sprintf('Error: mat file does not exist:\n%s', fullFileName);
  uiwait(warndlg(warningMessage));
  % Assign defaults in case we want to try to continue;
  a = 1;
  b = 2;
end
Actually, in my code I make it even more robust. I check if the structure has the field before trying to assign it. Let me know if you want that code.
