一下帮助,你会发现:
X,Y
—
Sample

|
vectors
Sample
grid
points,
specified
as
real
matrices
or
vectors.
If
X
and
Y
are
matrices,
then
they
contain
the
coordinates
of
a
full
grid
(in
meshgrid
format).
Use
the
meshgrid
function
to
create
the
X
and
Y
matrices
together.
Both
matrices
must
be
the
same
size.If
X
and
Y
are
vectors,
then
they
are
treated
as
a
grid
vectors.
The
values
in
both
vectors
must
be
strictly
monotonic
and
increasing.
也就是说
要求你的x,y严格单调,所以你的x是不符合要求的,因此报错
