All MATPOWER functions contain their own documentation, available by typing, for example ‘help ext2int’. Or you can look it up in the MATPOWER Online Function Reference <http://www.pserc.cornell.edu/matpower/docs/ref/> listed in the documentation section of the MATPOWER home page <http://www.pserc.cornell.edu/matpower/>.
Here’s the direct link for ext2int.m: http://www.pserc.cornell.edu/matpower/docs/ref/matpower6.0b2/ext2int.html The differing dimensions has to do with the fact that (from the above docs): "all isolated buses, off-line generators and branches are removed along with any generators or branches connected to isolated buses" Ray > On Dec 11, 2016, at 11:02 PM, 郭贤 <guoxian2...@gmail.com> wrote: > > Hi, > > Sorry to bother you.
