Hi all,
I have a set of x,y,z data as follows:
x =
0.1 0.31623 1 3.1623 10
y =
-1 -0.75 -0.5 -0.25 0 0.25 0.5 0.75 1
z =
0.36602 0.1774 0.18262 0.22931 0.23142
0.35639 0.28053 0.26868 0.26152 0.22932
0.41203 0.36037 0.3113 0.26592 0.21948
0.42282 0.36818 0.30538 0.25642 0.20567
0.34572 0.31703 0.28316 0.24251 0.19116
0.28834 0.28187 0.26377 0.2291 0.17855
0.27488 0.26436 0.24923 0.21842 0.16904
0.25749 0.25185 0.23936 0.21088 0.16254
0.24742 0.24423 0.23309 0.20598 0.15839
I plot a surface using this:
K>> surf(x, y, eSurf)
K>> view(2)
Matlab gives me this plot:
we can see that the blocks are rectangular but the entire plot is square, is there a way to make the blocks square but the plot rectangular?
Many thanks!

pcolor(x, y, z)
set(gca, 'XScale', 'log', 'dataaspectratio', [10 1 1])

You can use surf(x,y,z); view(2) instead of pcolor(x,y,z)
