MATLAB: Sorting structure with vector field

Question

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.

Answer 1

Assuming that you want to sort by antecedent

[~, order] = sortrows(vertcat(A.antecedent));
A = A(order)
