MATLAB: Assign value to array structure

Question

Hi Everybody! I have an array of let's say 100 elements, each element is the same structure with like 10 fields. What I would like to do is to generate an array – cell or numeric – of the same length as the structure array and assign each elements to a specific field of the individual structures. Here is the solution with for loop, I'd like to make the same without looping:

BaseArray = struct('field_1',[],'field_c2',[],'field__3',[]); % struct to be used
StructArray(100) = BaseArray; % initialize
ValuesToAssign   = rand(100);
for k = 1:length(StructArray)
    StructArray(k).field_1 = ValuesToAssign(k);
end

Any advice?

Answer 1

Hi,

this should work:

valuesCell = num2cell(ValuesToAssign);
[StructArray.field_1] = valuesCell{:};
