An easy way is to create the struct array backwards: sa = struct([]); fork = 3:-1:1 sa(k).a = k; sa(k).b = rand; end Another option: sb = struct('a', cell(1, 3),'b', cell(1, 3)); % Now sb is a struct array of size [1, 3] with the empty fields a and ...
Construct the array of structs: %init struct rec.datarow = [1,2,3,4,5]; rec.datacol = [1,2,3,4,5]'; rec.name ='apple'; %init array of structs rec(2:3) = rec; Access fields name, datarow, datacol and last element of datarow of first struct. No problem here. ...
