I am using a camera to detect periodic illumination but the difference in camera pixel spacing and illumination period, the detected values are aperiodic. e.g. the circled values are displaced 1 index from the correct position. I want to write the values into another array such that these values are shifted to the correct position. Is there a good way to do this?

MATLAB find function: https://in.mathworks.com/help/matlab/ref/find.html
MATLAB meshgrid function: https://in.mathworks.com/help/matlab/ref/meshgrid.html
MATLAB sub2ind function: https://in.mathworks.com/help/matlab/ref/sub2ind.html
