You will have to clear a row or a column completely
to remove row
a=[1 2 3;4 5 6; 7 8 9]
a(2,:)=[] % remove 2nd row
to remove column
a=[1 2 3;4 5 6; 7 8 9]
a(:,2)=[] % remove 2nd column
otherwise you need to convert them to NaN if removing individually
a=[1 2 3;4 5 6; 7 8 9]
a(2,2)=NaN % convert 2nd row 2nd col to NaN
