grid data
I have grid data in two dimensions A(0:99,0:99). I want to work on a similar grid data but in a big size ,i.e., A(0:100,0:100), how can I make the extension?
I done the following but not sure if it is right: do 12 i=0,99 do 12 j=0,99 12 a(i,j)=a(i,j) do 13 i=0,99 13 a(i,100)=a(i,0) do 14 j=0,99 14 a(100,j)=a(0,j) a(100,100)=a(0,0) Please help me if I am in a wrong way. Thanks. |
Hello,
you need to use some interpolation formula, do you have structured Cartesian grids ? Do |
Yes I have structured Cartesian grids.

You are lucky, you can use a built in Matlab function to interpolate between your grids:
http://www.mathworks.com/access/help...f/interp2.html If you don't have a Matlab license you can use Octave (which is an Open Source Matlab replacement and works on all major operating systems and it is free): http://www.gnu.org/software/octave/d...rpolation.html Or possible Fortran: http://people.sc.fsu.edu/~burkardt/f...al/alscal.html Hope this will help, Do |
Thank you very much Do for your help.
