Hi,
What is the context equivalent of latex's substack? How do I type the following $$ \sum_{\substack i \in P \\ j \in Q} a_{ij} $$
Where is that defined? LateX gives me and 'Undefined control sequence', and with \usepackage{amsmath} I get no error, but not a stack either. The definition from m-newmat is at least partly superceded by the new core math definitions Hans added last week, so a new implementation would be better. Cheers, Taco
