Answer 1

[Doug Hull]

There is no command cell2str in core MATLAB.

[Walter Roberson]

And string objects did not exist in MATLAB until R2016b.

Answer 2

[Matt J]

Perhaps you are thinking of

     >> cell2mat(str)

    ans =

    thisisatestofcell2str

or maybe

    >> char(str)

    ans =

    this
    is  
    a   
    test
    of  
    cell
    2   
    str

Answer 3

[Pascal Boulos]

>> join(str)

ans =

string

    "this is a test of cell 2 str"

>> strjoin(str)

ans =

 'this is a test of cell 2 str'

[Walter Roberson]

Note that string objects did not exist before R2016b.
