Hi! I'm working with a Radar image and I want to unwrap the interferometric phase of the image. I'm using the unwrap command but when I plot the image, the image is not correct. If I choose a random column on the image, I'm able to plot the unwrapped phase but what I want to do is plot unwrapped phase of the entire image. Can somebody help me with this?

Be careful about row and column. unwrap() applied to an array unwraps along the first non-singleton dimension, which would normally be the first dimension, so unwrap would normally proceed column by column. That can be a problem if you need to unwrap along rows. You can use unwrap(YourArray, [], 2) to unwrap along rows.

I tried using unwrap(image,[],2) and I'm having the same errors I have seen before but on the rows this time. I don't know what I could be doing wrong.
