There exists the share package amatrix which allows for collective
assignment to rows, columns, or subsets of rows or columns specified
by a list of indices or a Boolean expression. I got most of the way
through the implementation, but for better or worse, amatrix objects
are distinct from matrix, so existing Maxima functions which work on
matrix don't know anything about amatrix.
FWIW
