Highly unusual and not recommended: "Avoid using cell arrays of strings. When you use cell arrays, you give up the performance advantages that come from using string arrays."
The best solution is to avoid creating this cell array in the first place, and instead store the data in a string array (or as a cell array of character vectors) right from the start. How was this cell array created?

The OP is valid. There could be situations where it is unavoidable. For example, reading in mixed data from an Excel spreadsheet using the readcell function.

S = {'Hello',' ','world',' ','i',' ','am',' ','here'}
ss = [S{:}]

Those are character vectors, not strings:
S = {'Hello',' ','world',' ','i',' ','am',' ','here'}
ss = [S{:}]
class(ss) % definitely not a string array

Any valid answer to this question? OP wanted to convert to an array of strings, not a single vector of char. I have a similar problem.
S = {"Hello"," ","world"," ","i"," ","am"," ","here"}.'
SA = reshape([S{:}], size(S))
