I have an equation with three cases.. something like
d_i,j = a if blah1
b if blah2
c if blah3
Raphael,
I use a left curly brace followed by a vector (matrix with one column and three rows). You can always refer to them as "when a ...", "if b ..." and so on.

It wasn't actually exactly I described it. I have attached an example in lyx. I would like to add labels like (1), (2) ,(3) to the three cases so I can refer to them later. Are you saying that I should redo it as a matrix and then I could add the labels that way?
Cheers, Raphael
