That's unreadable because of indecipherable characters like "¡Ã?". I suspect you're working with strings, too. That is, did you mean temp = {{"CEST-01-A-01", "CEST-17-A-06"}, {"CEST-01-A-02", "CEST-01-A-06", "CEST-02-C-06", "CEST-03-B-03", "CEST-03-G-07", "CEST-05-C-11", "CEST-06-A-09", "CEST-08-B-07", "CEST-09-A-02", "CEST-12-A-06", "CEST-12-G-11", "CEST-16-C-02", "CEST-16-H-04", "CEST-17-A-04", "CEST-18-D-05", "CEST-19-C-01", "CEST-19-D-04", "CEST-19-G-01", "CEST-20-C-09", "CEST-20-G-08", "CEST-22-D-07", "CEST-22-D-11", "CEST-23-C-09", "CEST-26-G-08", "CEST-27-E-04", "CEST-27-E-12", "CEST-30-C-08", "CEST-30-E-03", "CEST-34-C-06", "CEST-34-F-04", "CEST-35-G-09", "CEST-36-A-01", "CEST-36-B-01", "CEST-37-F-03", "CEST-37-F-06", "CEST-45-A-10", "CEST-45-H-05", "CEST-46-D-03", "CEST-46-D-11", "CEST-48-D-01", "CEST-48-E-01", "CEST-50-E-09", "CEST-51-A-01", "CEST-51-C-09", "CEST-53-G-01", "CEST-54-C-12", "CEST-54-H-11", "CEST-55-E-01", "CEST-55-G-06", "CEST-57-C-12", "CEST-57-E-12", "CEST-59-F-05"}, {"CEST-01-A-04"}}; rather than what you posted, without quotes? Post in InputForm by either converting cells to InputForm (select the cell and select menu options Cell>Convert to>InputForm, or select the cell and push Ctrl-Shift-I) or use the "Copy as InputForm" palette: http://www.eclecticdreams.net/DrBob/copy_as_inputform.htm Bobby On Wed, 19 Jan 2005 02:00:24 -0500 (EST), Todd Allen <genesplicer28 at yahoo.com> wrote: > Hi everyone, > > I was hoping the usergroup might have some > thoughts on a peculiar error message I have been > receiving from Mathematica V 5.1(win XP). > > I have a set of nested loops where I try to > compare the elements of two matrices using > Intersection, and if there is indeed an intersection, > make a change to one of the matrices.
