Declaring a symbolic array real

Hello,

Hello I'm trying to create a symbolic array and ensure that it is real. When I use the code:

List = {'x','y'}
A = sym(List,'real')

the array A is not real and A' yields unwanted conjugates. Why doesn't this code ensure that A is real, and how can I fix it?

Thank you, Kevin

Using a cell array as the first argument to sym() is not a documented usage for any functionality of sym()

You can

sym('literalvariable', 'real')

and you can

sym(ExistingSymbolicArray, 'real')
