I just wrote a recursive function which create a structure nested by the fieldnames given by an array but it doesn't work

if true
  % code
function addfield = add(var,fields)
       C =  {[]}; 
        if numel(fields)>0
           k = fields{1};
           field = {k};
           var =  cell2struct(C,field,2);
           fields(1)=[];
           addfield =  var.(k);
           add((var.(k)),fields)  ;  
        end
        addfield = var;

end end

my idea is to create the structure var and to initiate var.field1.field2.field3...fieldn= [] with fields = {fields1,field2,...,fieldn}

The simple MATLAB approach is to use SETFIELD() with a comma-separated list:

C = {'f1','f2','f3'};
V = pi;
S = struct();
S = setfield(S,C{:},V);

Checking the structure content:

S.f1.f2.f3

ans = 3.1416
