Method on @sym: subsindex (x) ¶

Operator on @sym: A(sym(x)) ¶

Used to implement indexing by sym.

Note returns zero-based index.

This function should not need to be called directly, but it is used internally, for example in:

A = sym([10 11]);
A(sym(1))
  ⇒ (sym) 10

A(sym(2)) = sym('x')
  ⇒ A = (sym) [10  x]  (1×2 matrix)
