Hi Bill,

an error occured if the function was called with the string option values 'UniformOutput' or 'ErrorHandler', it didn't matter which value for one of these options was set. Then I saw something like octave_base_value::cell_value invalid conversion (if I remember correctly). The other changes in the changeset just are there because of replacements of tabs with spaces ;)

Regards,

  Thomas
