Actually, it is not a cell array of strings anymore (because I converted some of the strings to NaN), but it is a cell array
Splitting cell array of both strings and numbers by a delimiter

Hello,
I have a cell array that consists of both strings and numbers. I need to split into two different columns by the delimiter '~' However, I am not able to use regexp, as the cell array must all be strings. And I can't use num2str or str2num because half are strings and half are numbers, and it creates an error message. I am attaching my .mat file so you may get an idea of what I'm working with.
Please let me know what I can do to split this cell array into two different columns by the delimiter '~' For the elements that are NaN, I would like both columns to say NaN
Thank you for your help,
Melissa

Or you can do what I've done in my answer below.
In any case, when processing data, it is better to always generate that data in a consistent way. In your case, that means always have string consisting of two numbers surrounding ~, even if these numbers are NaN. That is, you would have been better off writing 'NaN~NaN' in your cell array instead of 'NaN' or NaN.
Side note: there's no need to escape ~ in the regular expression. I'm surprised matlab accepts it.

The simplest thing would be to convert these NaNs into strings of 'NaN~NaN' and then use the same algorithm as in my previous answer to convert the cell array:
Depthcm(cellfun(@(x) isnumeric(x) && isnan(x), Depthcm)) = {'NaN~NaN'};
splitdepth = regexp(Depthcm, '~', 'split');
bounds = str2double(vertcat(splitdepth{:}));
