Alok, sure, just trying to help here.
If you can kindly explain what you mean by "gone". If you mean empty cells, have you ever tried to create a "matrix" with an empty cell? If you are okay with any other format, like string, you can use fillmissing() to fill in spaces. Are you looking for something like that?
blah = string(Phase_data);
blah = fillmissing(blah,'constant',"");

Thanks for the prompt reply Ridwan. So, if you open the attched mat file, you'll see that the matrix contain NaNs. I was wondering if it is possible to replace (remove) NaNs and have 'empty cells' instead. I tried fillmissing but as you said, we end up with a 'string' which I don't want.
What I was wondering is if we can we can use something like:
Phase_data(isnan(Phase_data))='empty cells';
Sorry, I'm stuck.

Nope, I don't think that's possible. Sorry.
