Hi all!
I have a matrix with various shapes. The matrix looks something like this (picture included below) when I use the imshow command. I was wondering if anyone knew how to outline the shapes so that only the outline of the shape (i.e. the boundaries) appears. I tried using contourf, and it works, but this flips the image upside down. Any other options?
I have included some code for reference:
shape = ncread(file, 'shape', [1,1,1,612,1], [inf, inf, inf, 1, inf])
imshow(shape)
contourf(shape)
Thanks in advance!

Try this:
figure
contourf(shape)
set(gca, 'YDir','reverse')
axis('equal')
That should fiip it right-side-up.
