I need to perform phase unwrapping in 2D using MATLAB, but the unwrap function seems to work only in 1D.
I want to have a routine similar to this one, available in a Python library:
Any suggestions?

Depending on what your data looks like, you may be able to simply use "unwrap" on the two different dimensions.
A = unwrap(A,[],1);
A = unwrap(A,[],2);
This is not generally true however, to unwrap data in two dimensions may need more advanced algorithms; unfortunately these are not built into MATLAB.
There are a number of user submitted functions on MATLAB central though which may help your further: https://in.mathworks.com/matlabcentral/fileexchange/?utf8=%E2%9C%93&term=phase+unwrap
Note that MathWorks does not offer support on MATLAB Central submissions. For help or comments on functions provided on MATLAB Central please contact the authors of the functions.

Using unwrap twice doesn't work. I will try the user submitted functions on MATLAB central. Thank you for your help.
