Method behinds "interp2" command

I always use interp2 to interpolate my data in MATLAB. But I want to know what kind of algorithm is really used when running that command, such as Local Weight Regression (LWR) or something.

If you type doc interp2, you'll see that you can specify one of four different methods that interp2 can use: nearest neighbour interpolation, linear interpolation, cubic spline interpolation, or cubic interpolation.

If you don't specify one of those explicitly, it will use the default method, which is linear interpolation.
