I want to sort a field structure that is a vector field. You can see in the image.
I tried the following method but it doesn't works.
D=struct2cell(A) tam=size(D) D = reshape(D, tam(1), []) D=D' D=sortrows(D,1)
when I do the last command matlab error message apears:
Error using sortrows>sort_cell_back_to_front (line 130) Some cells in X contain non-scalar values and cannot be sorted.
Error in sortrows (line 88) ndx = sort_cell_back_to_front(x_sub, col);
I think it's because the first field is a vector field of type double.
How can I solve this?
Thanks in advance.

Assuming that you want to sort by antecedent
[~, order] = sortrows(vertcat(A.antecedent));
A = A(order)

@alfred, I don't understand what you mean by "I want that the column consequent change with the same rows of antecedent, because any row of antecedent have his consequent value". Can you show an example of input and desired output?
[~, order] = ...
the ~ means: I don't care about this output. You only want the second output of sortrows, the order of the indices.

@Guillaume, Sorry how i said before i have seen that the consequent change with antecedent 1 by 1. then i answerd me...
And i don't understand totally your answer.. because... this function ordered with first output too... or is what it seems... i tried to put all disordered and it works correctly. always put [1 1] in the first row then what you mean with first output?
I'm really confused..
