Prev: assigning a vector to the fields of a structured array

Having a structured array such as

sa=struct('field_a',repmat({2},100,1),'field_b',repmat({10},100,1));

%it is easily possible to assign all values of a particular field to an ordinary vector

a=[sa(:).field_a];

%How to achieve the opposite assignment? Unfortunatly
%[sa(:).field_a]=a;
% is an inalid syntax.

%Does anybody know how to assign each component of a vector to a field of a %structured array?

one of the solutions

sa=struct('field_a',repmat({2},100,1),'field_b',repmat({10},100,1));
v=1:numel(sa);
v=num2cell(v);
[sa(1:end).field_a]=deal(v{:});
sa(4).field_a
% ans = 4
