Error: Inputs must be character vectors, cell arrays of character vectors, or string arrays.

Here is an example of my Variable A:

A=
"33RO30160505"
"33RO30160507"
"33RO30160508"

isstring(A) = 1.

However, I keep getting the error below:

Error using string/strcat (line 33)
Inputs must be character vectors, cell arrays of character vectors, or string arrays.
Error in initialLoading (line 196)
L2 = strcat('CODE: [', A(1), ...
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Does anyone know what is going on here?

I am not certain what result you want, however for string arrays, you can just use arithmetic operators.

Try this --

A = ["33RO30160505"
     "33RO30160507"
     "33RO30160508"];

L2 = "CODE: [" + A +"]"

L2 = 3×1 string array
    "CODE: [33RO30160505]"
    "CODE: [33RO30160507]"
    "CODE: [33RO30160508]"

.

Many thanks for the reply. I need to specify only one of the codes.

How do I do that? For example, A(1) does not work. Neither does A{1}. They trigger the error I mentioned above.

It should.

Try this --

A = ["33RO30160505"
     "33RO30160507"
     "33RO30160508"];

L2 = "CODE: [" + A(1) +"]"

L2 = "CODE: [33RO30160505]"

.

It turns out that the error was caused by another variable being numeric instead of a string. Sorry about that. Many thanks for your help anyway.

As always, my pleasure!
