Spatial_detect is a Matlab script to extract across-wafer variation from measurement data. It assumes the across wafer variation to be a quadratic function. In this detection, we have two different spatial variation models: 1) Random field based spatial variation model [1, 2]; 2) Modeling across-wafer variation [3]. In practice, modeling across-wafer variation is more accurate and efficient than the random field based spatial variation model. The current release includes source code, user manual, and sample input files.
