what coordinate system do x and y have to be in when using scatteredinterpolant in matlab

main.m
% Generating sample data
x = [0; 1; 2; 3; 4]; % column vector
y = [0; 1; 2; 3; 4]; % column vector
z = [1; 4; 9; 16; 25]; % column vector

% Creating a scattered interpolant
F = scatteredInterpolant(x, y, z);

% Evaluating the interpolant at a specific point
queryX = 2.5;
queryY = 2.5;
result = F(queryX, queryY);
disp(result);
