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.

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{:}]

Just a point of clarification. ss is a character array while str is a string. A few versions ago, MATLAB made these different types of variables, though in common speech, people call either one "strings".
