A section on optimization would be nice, but I am not sure if it could be done with sufficient generality without getting too long (and complicated) ?

Looking back at what is present, I think logical arrays should be emphasized a bit more: we describe what they are but we don't push the efficiency. We also should probably have a topic about working conditionally on vectors (e.g, all those people trying to "if x < 5" when x is a vector). And a topic about what "if " means in MATLAB when is a vector or array. Umm, and maybe a brief topic about detecting/converting non-0's, showing (e.g.,) X.
