contour plot in matlab

I have Matrix B of size 8 x 72. this belongs to the data collected at difefrent axial heights (y) and radial(x) positions.

For e.g. in the matrix B , the coulmns from 1:12 pertains to y = 10 mm and x = 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 60 and so on for y = 20 , 30, 40 , 50 , 60 etc.,

Any idea how to plot this data using contour ()

It might help if you post the data.

Also, what about the rows? Are they just repeated measurements for the y and x conditions you identify along the columns?

Hi,

Here is the attachment of matrix B that contains the data

Yes, actually row again represents radial position of 3 mm with 8 divisions for e.g. coulmn 1 of row 1 to 8 represents 0, 0.43, 0.86, 1.29,1.7, 1,2. 1,2. 57, 3; coulmn 2 of row 1 to 8 represents 3 to 6 mm with 8 divisions...

After getting a matrix, use Contour.

B = B' ; 
[r,c] = size(B);
lay = 10:10:60 ; 
nlay  = length(lay) ;
out   = permute(reshape(B',[c,r/nlay,nlay]),[2,1,3]);
for i = 1:size(out,3)
    figure(i)
    contour(out(:,:,i))
end

Hi,

Actually, I am looking for final image something like this

I fiddled with your data a bit, but couldn't manage to create a figure like the one you posted. Was the posted figure created in MATLAB?
