I have the following code:

    function x = rZ(delta, aSqr)
    load(delta);
    load(aSqr);
    x = delta./aSqr;
    end

Where delta and aSqr are .txt files I have loaded in containing double workspace variables. When the function is ran in the command window the following error is thrown up:

    Error using rZSum (line 2)
    Not enough input arguments.

Would anyone be able to advise me on where Im going wrong? Thank you in advanced.

The error refers to a function rZSum which is nowhere to be seen...

Need the error in context of the actual session that generated it.

Also, as written function rZ arguments delta and aSqr would have to be existing filenames (which I guess maybe is what your description means, not already loaded?) If you've already loaded them, then you don't need the load again.

Try something like (untested)

% Inputs: two strings that are filenames.
function x = rZ(delta, aSqr)
  try
    x = []; % Initialize.
    s1 = load(delta); % Load variables in the delta file into the s1 structure.
    s2 = load(aSqr); % Load variables in the aSqr file into the s2 structure.
    % Now assume that there is a variable called delta in the delta mat file.
    % and a variable called aSqr in the aSqr mat file.
    % Divide them element by element.
    if size(s1.delta) == size(s2.aSqr)
       x = s1.delta ./ s2.aSqr;
    else
       errorMessage = sprintf('Error size of delta does not match size of aSqr.\Cannot divide them')
       uiwait(warndlg(errorMessage));
    end
  catch ME
  errorMessage = sprintf('Error in function %s() at line %d.\n\nError Message:\n%s', ...
    ME.stack(1).name, ME.stack(1).line, ME.message);
  fprintf(1, '%s\n', errorMessage);
  uiwait(warndlg(errorMessage));
  end
