Thanks! You have found the solution.
Maybe there is a problem with the help file here: when you ask help with
help -i expressions
this is what you get:
A special form of indexing may be used to select elements of a
matrix or vector. If the indices are vectors made up of only ones and
zeros, the result is a new matrix whose elements correspond to the
elements of the index vector that are equal to one. For example,
a = [1, 2; 3, 4];
a ([1, 0], :)
selects the first row of the matrix `a'.
But as you have seen this is not true (and that was my problem), because
you need to introduce some kind of logical operator. Maybe this was the
way
it worked in older versions (at least, this is the way it worked in a
very old matlab version), and now it has been changed...
thanks again
