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
