Could you upload the code so that the pattern is observed and an alternative solution can be given?

x=[1,8,2,8];
y=[2,3,0,9];
z=[80,30,30,40];
[X,Y]=meshgrid(x,y) ;
F = scatteredInterpolant(x',y',z') ;
Z = F(X,Y) ;
u=trapz(x,Z,2)
I=trapz(y,u)

Was thinking the same but https://www.mathworks.com/help/matlab/ref/scatteredinterpolant.html interpolates data right kssv? asking out of curiosity because your an expert in this.

Yes it interpolates the scattered data.

It was confusing because OP mentioned "function instead of grid data without Interpolation" so I thought there is some function which doesn't interpolate data similar to griddata() or scatteredInterpolant()?
