YourStruct = struct('A', {cell(20,1)}, 'B', {zeros(20,1)}, 'C', {zeros(20,1)}, 'D', {zeros(20,1)}, 'E', {zeros(20,1)}, 'F', {zeros(20,1)});

Or if you prefer,

YourStruct.A = cell(20,1);
for FN = 'BCDEF'
  YourStruct.(FN) = zeros(20,1);
end

FN = cellstr(('A':'F')');
d = [FN'; repmat({zeros(20,1)},1,numel(FN))];
YourStruct = struct(d{:});

Looks like that would miss that A should become cell(20,1)
