Phase_data.mat

I've a matrix which looks like the one attached. How do I replace NaNs with blank spaces without altering anything else?

Thanks in advance.

I believe you are looking for fillmissing() or rmmissing():

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.
