this error appear during the run of my program
"Cell contents reference from a non-cell array object."cell
U=[ ]
S={1 ,2 ,3}
for i=1:numel(S)
U=[U S{i}];

U = unique(U,'first');

Two options that come quickly to mind:
S={1 ,2 ,3};
U = [S{:}]
U = cell2mat(S)
Obviously these only work if the cell contents can be appropriately concatenated. If they cannot be, it is best to leave the cell array as a cell array, and address its contents as needed.

The code you posted runs without error in R2019b, as does the code I posted.
