Do you want to access an element of an array, or use the 1 as subscript in a title or label of a diagram?

x(1)

These are things you should try! If you think it is that, then try it! That form of a subscript will fail of course, but you would learn something. Experimentation in a tool like MATLAB is the way to learn.

Subscripts for arrays (and vectors, a subset of arrays) are done as x(1).

Subscripts for cell arrays, you do as x{1}, thus curly braces.
