How to convert a 1x1 cell to a string?

How to convert a 1x1 cell like {'line'} to a character vector like 'line', or a string like "line" please. thx

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.

Thanks. It works.

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 = 
    "one"
 >> string({'one','two'})
 ans = 
  1×2 string array
    "one"    "two"

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{:}]

[Image Analyst]

Is this what you mean?

ca = {'Hello',' ','world'} % Cell Array.
charArray = [ca{:}]
str = convertCharsToStrings(charArray)

If not, start a new question and give your starting cell, and expected output.

[Morteza Darvish Morshedi]

Maybe you are looking for this:

S = {'Hello','World'};
s2 = cell(1,length(S)); s2(:)={' '};
ss = [S;s2];
ss = [ss{:}]

[Image Analyst]

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".

[Morteza Darvish Morshedi]

Right. Thanks.
