Interpolation problem with interp2
显示 更早的评论
Hi everyone!
I did some computations on a grayscale picture and I would like to interpolate some points in my matrix. My problem is that interp2 doesn't allow to do what I want to.
Let's say my matrix is im
im = [1 2 3; 4 nan 6; 7 8 9];
and when I do:
[colum row] = meshgrid(1:3,1:3);
colum_i = 2;
row_i = 2;
zi = interp2(colum, row, im, colum_i, row_i);
I would like that it interpoles the nan. Is there a way to redefine a point in the matrix instead of a point between the points of the matrix?
My picture is a 512x512 pixels and interp2 would be very useful and fast instead of computing for every point separately...
Thank you for yours answers.
Regards, D.

Walter, you are typing faster than me - yesterday, today and tomorrow. It would increase the efficiency of my work, if a small icon appears in the question to show, that you are reading it currently - and will have answered it some seconds later.
