% psychlasterror - Replacement for Matlab-7 'lasterror'.
% This is hopefully useful for older Matlab installations and
% for the Octave port:
%
% If the 'lasterror' variable, M-File or builtin function
% is supported on your Matlab installation, this function
% will return it.
%
% Otherwise, this function will return the older lasterr
% variable instead.
% exist must check for all cases, as lasterror is implemented differently
% on different Matlab versions (variable, M-File or builtin-function):
if exist('lasterror') > 0 %#ok<EXIST>
% Call Matlab implementation:
if nargin > 0
try
rc = lasterror(varargin{1});
catch
% This catches bugs in lasterror on Matlab 7.0 itself!
% Doesn't recognize the 'reset' keyword!
try
if strcmpi(varargin{1}, 'reset')
lasterr('');
else
lasterr(varargin{1});
end
catch
% The climax of sadness!
end
end
else
rc = lasterror;
end
else
% Use our simple fallback-implementation:
rc.message = lasterr;
rc.identifier = '';
if nargin > 0
if strcmpi(varargin{1}, 'reset')
lasterr('');
else
lasterr(varargin{1});
end
end
end
