Set object identifiers
A = SETIDENT(A,IDENT,FIELD,L)
Set or reset the subfield FIELD of the ident field of A by IDENT. IDENT should be an array of size (N,K), with arbitrary K.
Note the ident field of datasets was originally intended for an identification of the individual objects. Later its usage was extended to a field for storing general information on objects. For that reason 'old' datasets without a structure in the ident field are transformed such that this information is stored in a subfield IDENT in the ident field. It can be retrieved by GETIDENT(A,'IDENT').
The default FIELD is 'IDENT'. To reset the entire IDENT give A = SETIDENT(A,IDENT,''), in which IDENT is a structure array of the right size and including a subfield named also IDENT.
The new structure is checked or created by A = SETIDENT(A);
Note also that for reasons of backward compatibility the parameter order of the SETIDENT command differs from similar Matlab commands like SETFIELD: first field content, then field name.
