Save string in structure

Hi everyone. I'm trying to save string in a structure, but MATLAB shows me an error.

for i=1:3
  file=strcat('Documento',num2str(i),' - by Gennaro');
  struttura.nome(i)=file;
end

How can I do it?

Thank you very much.

struttura.nome(i)

allcoates to one element of an array (the field nome). Presumably the strings has multiple elements, in which case this allocation will be an error. If you want to allocate a non-scalar char array (string) then you will need to use the correct indexing (e.g. using colon), or allocate by redefining that field entirely.

Ok, I solved problem:

for i=1:3
file=strcat('Documento',num2str(i),' - by Gennaro');
struttura(i).nome=file;
end

Thank you anyway.
