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.
