Try it like this:
try
% No error yet, so try to run algorithm 1
algorithm1();
catch ME
% You get here if algorithm 1 bombs.
% Create an informative error message.
errorMessage = sprintf('An error occurred in function blah_fubar(). The error reported by MATLAB is:\n\n%s\nClick OK to run algorithm2()', ME.message);
% Print error message to command window.
fprintf('%s', errorMessage);
% Alert the user via a popup message.
uiwait(warndlg((errorMessage));
% Now run algorithm 2, because we had the error occur.
algorithm2();
end
