The apply_changes() function can be used to disable branches and buses by
setting the BR_STATUS to column to 0 for a branch or the BUS_TYPE column to
NONE for a bus, but it cannot be used to actually delete rows from the branch
and bus matrices.
For example, to disconnect branch 3 and bus 4, you could use the following ...
define_constants;
chgtab = [ ...
1 0.1 CT_TBRCH 3 BR_STATUS CT_REP 0;
2 0.1 CT_TBUS 4 BUS_TYPE CT_REP NONE;
];
Hope this helps,
