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.
This is defined in amsmath. Sorry, I made a mistake in typing. It should be $$ \sum_{\substack{ a \\ b}} c $$
The definition from m-newmat is at least partly superceded by the new core math definitions Hans added last week, so a new implementation would be better.
Can you suggest something? -- Aditya Mahajan, EECS Systems, University of Michigan http://www.eecs.umich.edu/~adityam || Ph: 7342624008
