Indexed empty matrix:
The Individual elements cannot be eliminated from matrices, as matrices always have the similar number of elements in every row.
>> mat = [7 9 8; 4 6 5]
mat =
7 9 8
4 6 5
>> mat(1,2) = [];
??? The Indexed empty matrix assignment is not permitted.
Though, whole rows or columns could be removed from a matrix. For illustration, to remove the second column:
>> mat(:,2) = []
7 8
4 5
