You need to extract the information from the object using its methods and properties (call METHODS and PROPERTIES on the object) and then write that data out using an appropriate format. Alternately, would saving the object to a MAT-file be sufficient for your needs? That way, you can LOAD it in a later session and use the stored object. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com
