Is this a function that only helps you know which pattern and variables belongs to which raw material? or is it somehow implemented as a bigger matrix?<br />Thanks, DanDaniel Ríos Pavíahttps://www.blogger.com/profile/04943406648233216473noreply@blogger.comtag:blogger.com,1999:blog-593563533834706486.post-50980146840151921452010-07-14T18:04:37.057-04:002010-07-14T18:04:37.057-04:00I think that would require some thought.
