I have an input argument that is a 1x1 struct
this is my code
function escrevecircuitos(circuito, fid)
if fid == 1 fprintf(fid,'%8s %13s %2s %2s %9s %7s\r\n', 'circuito', 'nome_ficheiro', 'SE', 'ID', 'Perimetro', 'Recorde'); for i = 1:length(circuito) fprintf('%20s %14.1s %2.6f %1.6f %2.6f %1.6f %4d %1:2:3f\r\n',circuito(i).circuito,circuito(i).nome_ficheiro,circuito(i).SE(1),circuito(i).ID,circuito(i).Perimetro,circuito(i).Recorde); end end
How can i solve the problem,the error is
Error using fprintf Function is not defined for 'struct' inputs.
Error in escrevecircuitos (line 7) fprintf('%20s %14.1s %2.6f %1.6f %2.6f %1.6f %4d %1:2:3f\r\n',circuito(i).circuito,circuito(i).nome_ficheiro,circuito(i).SE(1),circuito(i).ID,circuito(i).Perimetro,circuito(i).Recorde)
Thank you for the help

That looks okay at the moment, unless one of the fields inside circuito is itself a structure. Perhaps circuito(i).circuito or circuito(i).Perimetro
Try this to help debug
fn = fieldnames(circuito);
for K = 1 : length(circuito)
for f = 1 : length(fn)
if isstruct( circuito(K).(fn{f}) )
fprintf('Index %d field %s is structure\n', K, fn{f} );
end
end
end
