Hello,
In another post I asked about interpolation and sampling and I got some
good response. After reading them, I am now interested in non uniform
sampling and interpolation. What I am interested is to solve following type
of problems:
Assuming I have a 1D signal that the value of it is known at n=[1 3 4 6 9
10 15 19]. I want to calculate the values at other points {n=[0 2 5 6 7 8 11
12 13 14 16 17 18 20]) . I think I can do this in by interpolation. Since
the distance between samples that I have are non uniform, I can't use normal
interpolation and I should use some non uniform interpolation technique.
Where can I find more information on this subject? A paper or tutorial is
very good.
How can I do this in 2D?
Is there any Matlab code that implements these types of interpolations?
Especially 2D interpolation.
Best regards

Hello MA,
An all around basis can be found in a paper titled "A Chronology of
Interpolation" Just google for it and you should find a .pdf version
you can download. This paper is excellant for providings methods and
their references.
IHTH,
