19.07.2018 · value = getfield(S,field) returns the value in the specified field of the structure S.For example, if S.a = 1, then getfield(S,'a') returns 1.. As an alternative to getfield, use dot notation, value = S.field.Dot notation is typically more efficient. If S is nonscalar, then getfield returns the value in the first element of the array, equivalent to S(1).field.
