To convert a cell array of character vectors to a character array, use the “char” function.
A = {'line'}
B = char(A)
To extract the contents from a cell, index using curly braces.
A = {'line'}
B = A{1}
Starting in R2016b, you can store text in string arrays. To convert a cell array to a string array, use the “string” function.
A = {'line'}
B = string(A)
For more information, please refer to the MathWorks documentation on Cell Arrays of Character Vectors and Text in String and Charater Arrays.

That's a piece of cake. Thanks a lot!

Azzi showed you how to extract the string from a cell. Another way is to convert the cell with char():
ca={'line'} % This is our cell array.
str = char(ca) % Convert it to a character array (string).
Net, both give the same result, just different ways of getting there. If your cell array is only a single solitary cell, then you should not even use a cell in the first place - use a string.

Even if you have more than 1 string in our cell array, an easy way can be:
S = {'Hello',' ','world'}
ss = [S{:}]

Right. Thanks.
