Hello,
I think that there may be some wrong in the contour function
which is in the plot toolbox, as the contour it's show
doesn't be uniform with the data.
The following image show the wrong result of a two cells
image.

Since contour is a core octave version, can you please post a
complete bug report [1] that we can reproduce the error (in a
first step). What is your octave version?

Hi,
I have experiment the contour function again yesterday, and if
the code as following is wrong, always rise many level lines.
the code(the u matrix is u matrix):
figure, contour(u, [0 0]).
However, If I modify the code as following , the result is good.
the modified code:
[nrow ncol] = size(u);
figure, contour(1:ncol, 1:row, u, [0 0])
As description by the manual, it should be same whatever the x
and y be transfered to contour function, that's why ?

As I said, to help you we need first a complete example that we
can reproduce. So, please file a report at the bug tracker. What
is your octave version?
Kai
My octave version is 3.2.4.
