Can some tell me a work around ? looks like a bug.
my code which works on matlab 2007b,2008b has some portion which does this row deletion.
now I have problems with 2009b

Yes, looks like a bug. It works ok on my matla 2008b

EDU>> syms a b c d e f g h
x = [a,b;c,d;e,f;g,h]

x(2,:) = []

x =

[ a, b]
[ e, f]
[ g, h]

Make a bug report to Mathworks.
