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)

If you are using a recent version of MATLAB you may find that a string or string array is more convenient then the character array created in the above example and by the char function:
>> string({'one'})
ans =
>> string({'one','two'})
ans =
1×2 string array
"one" "two"
it has done magic to me thanks a lot
Thanks Azzi Abdelmalek. Works perfect.

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.
