I am learning on phase unwrapping about InSAR, and now meet some difficulties. I do not know how to achieve Flynn algorithm under matlab. I need your help,if someone know this algorithm.

I know nothing about InSAR (sounds like a virus) or Flynn algorithm,
but are you aware of this:
help unwrap

UNWRAP is 1D. Robust unwrapping in 2D or more dimension is a much more complicated problem.

Do you have a paper that describes Flynn's algorithm?

The cousin of Flynn's is Costantini's, where below you can find an implementation:

Thank you very much!
maybe flynn algorithm can be described as Two-dimensional phase unwrapping with minimum weighted discontinuity.

here is a paper i learn now http://www.opticsinfobase.org/josaa/abstract.cfm?URI=josaa-14-10-2692

i want to compare some traditional phase unwrapping algorithms by simulink it through matlab
