PC-STEM
Package for strain mapping with scanning nanobeam electron diffraction in Matlab
ExampleStrainMap_PTODSO09.m is an example Matlab script showing how to use these functions
A detailed explanation of the theory behind PC (power cepstral) stain mapping analysis can be found in "The Exit-Wave Power-Cepstrum Transform for Scanning Nanobeam Electron Diffraction: Robust Strain Mapping at Subnanometer Resolution and Subpicometer Precision" at http://arxiv.org/abs/1911.00984
