 Hi, I have a problem regarding matrix handeling. I am working with a serie of matrixes containing several columns. Now I would like to delete those rows of the matrixes,that in one of the columns contain values less than 50 or greater than 1000. How would this be possible, I have tried to create a simple function for this, but I just don't seem to get it right.Thank you so much for your help, Monna
