Details:

Seems like meshgrid command unnaturally swaps X and Y data.

Proceed:

octave:43> [x, y, z] = meshgrid (1:5, 1:10, 1:5);
octave:44> val = rand (5, 10, 5);
octave:45> isosurface (x, y, z, val, .5);
error: __marching_cube__: XX, YY, ZZ, C must be of equal size
error: called from:
error:   /usr/share/octave/3.6.2/m/plot/private/__marching_cube__.m at line
107, column 5
error:   /usr/share/octave/3.6.2/m/plot/isosurface.m at line 157, column 32
octave:45> size(x)
ans =

   10    5    5

octave:46> size(val)
ans =

    5   10    5



while next code is Ok;


octave:47> [x, y, z] = meshgrid (1:5, 1:5, 1:10);
octave:48> val = rand (5, 5, 10);
octave:49> isosurface (x, y, z, val, .5);
octave:50> size(x)
ans =

    5    5   10

octave:51> size(val)
ans =

    5    5   10

octave:52> 


This is probably really minor, but annoying and could bring errors somewhere
else... Thank you!
