I want to call a field of a struct by a string variable named like that field, but I receive the error “Reference to non-existent field …”. How can I solve this problem? I mean how can I define a name of a field with a string variable and then add this string variable to struct to call the field?

A.B = 'B1'; % Assign the value B1 to field B
C = 'B' % Assign the value B to variable C
A.C % I receive the error “Reference to non-existent field 'C'.”
