#### 8.2.53.16 string.plus ¶

Method: `out =` plus `(a, b)` ¶

  String concatenation via plus operator.

  Concatenates the two input arrays, string-wise. Inputs that are not string arrays are converted to string arrays.

  The concatenation is done by calling ‘strcat‘ on the inputs, and has the same behavior.

  Returns a string array the same size as the scalar expansion of its inputs.
