Hey guys, so I got the following problem: I want to interpolate my matrix (size 220x180x1801) onto a new grid (of course size 220x180). So I am currently using griddata and it is pretty slow. It looks like this:

for i=1:length(time)
u_grid(:,:,i)=griddata(longitude,latitude,wind_x(:,:,i),lon,lat);
end

I wanted to try and use scatteredInterpolant, because matlab tells me it has a better performance. But when I try to use it, I get the error "The input points must be specified in column-vector format." So is there any way to use a matrix as input, because using another for-loop to do the column-vector stuff would probably slow down everything.
