run out of memory error when analyze large size SEM image

[ahnydd]

Hi Justin Blaber,

I am Dongdi Yin from Southwest Jiaotong University. We are working on HRDIC based on SEM. We have got very nice strain maps using Ncorr for small size SEM images (up to 6749x5229 pixels). However, when we tried to analyze larger size SEM images, such as 8818x6871 pixels, an error occurred, which seems a run out of memory error. The screenshot of the error message is attached below.
We are using MATLAB 2021b. 20 cores are set for the OpenMP multithreading.
The computer we used: Intel® Xeon® Gold 6230R Processor (35.75M Cache, 2.10 GHz, 26 cores)+192GB DDR4 memory.

Many thanks and Happy New Year!
Looking forward to hearing from you
Kind regards
Dongdi Yin
