How can I concatenate strings in a cell array with spaces between them in MATLAB?

Question

I want to concatenate (padding with spaces) the strings in a cell array {\'a\', \'b\'} to give a single string \'a b\'. How can I do this in MATLAB

Answer 1

Both join and strjoin are introduced in R2013a. However, the mathworks site about strjoin reads:

Starting in R2016b, the join function is recommended to join elements of a string array.

>> C = {'one','two','three'};
>> join(C) %same result as: >> join(C, ' ')

ans = 

  string

    "one two three"

>> join(C, ', and-ah ')

ans = 

  string

    "one, and-ah two, and-ah three"

Personally I like Alex' solution as well, as older versions of Matlab are abundant in research groups around the world.
