Hi, I have a 3d tecplot question, the x is 1:1:100,y=1:1:10,z=1:1:10,cc(x,y,z) is the 3d array with dimension (100,10,10). How should I organize the structure of the data so that I can plot it in tecplot? Anybody know how to plot the 3d contour in matlab? Thanks.

Jane

Please correct me if I am wrong. This should work for tecplot.

i - along x
j - along y
k - along z


print "Variables = x, y, z, cc"
print "Zone T = xyz, i=imax, j=jmax, k=kmax"
for k=1:kmax
for j=1:jmax
for i=1:imax
print x(i,j,k) y(i,j,k) z(i,j,k) cc(i,j,k)
end
end
end

Many thanks to Praveen and Mike, they work well.
