How to scatteredInterpolant bwtween data sets?

Hi,

I have two data sets, x1,y1,z1 (represnting a coordnates as xyz coordnates), and other data set v1, v2,v3 (reprenting a vector field).

I want to interplote the vector fileds into the x1 y1 z1 for each direction.

One of the suggestions is using scatteredInterpolant function.

V = ([v1 v2 v3]);
Fx = scatteredInterpolant(x1,V,'natural','nearest');
Fy = scatteredInterpolant(y1,V,'natural','nearest');
Fz = scatteredInterpolant(z1,V,'natural','nearest');

The problem is the hthe size of v1 v2 v3 are NOT the same size of x1 y1 z1;

Is there any way to overcome this issue?
