Hello All,
I did not find answers for my question, so I post it here:
I have a matrix of logical gridded data (0 or 1), how could I interpolate them to finer scale gridded data?
E.g., originally, it is X=[1:3:22];Y=[1:3:10]; DATA=[0 0 0 0; 0 0 0 0; 0 1 1 0; 0 1 1 0; 0 1 1 0; 0 1 1 0; 0 0 0 0; 0 0 0 0]; Now I want to interpolate DATA to a new data (also a logical matrix), with X=[1:22];Y=[1:10];
Since I use these data to describe the shape of something. If I use interp2 or griddata, the shape of the matrix will be distorted. I could, of course, write a for loop to check point by point. But I really wish there is another elegant way to deal with this simple problem!!!
Thanks a lot,
Laura
