For example,octave:1> a.b.c.d.e = 1;octave:2> aa ={b ={c ={d: 1x1 struct}}}This prevents long and confusing output from large deeply nested structures.struct levels to printBuilt-in VariableYou can tell Octave how many structure levels to display by setting the built-invariable struct_levels_to_print. The default value is 2.Functions can return structures. For example, the following function separates the realand complex parts of a matrix and stores them in two elements of the same structurevariable.octave:1> function y = f (x)> y.re = real (x);> y.im = imag (x);> endfunctionWhen called with a complex-valued argument, f returns the data structure containingthe real and imaginary parts of the original function argument.
