12 16;
14 9;
16 7;];
i want to delete 5th row the 15th column then
i want to delete 7throw the 5th column then
i want to delete 10row the 11 column then
i want to delete 11row the 13 column then
i want to delete 12row the 16 column then
i want to delete 14row the 9 column then
i want to delete 16row the 7 column then
what is the a logic?????? if i use for loop the array size is changed so its index out of bounds.......... But the array size of A matrix is changed .

Don't delete one-by-one. Instead, delete all rows at once, then all columns at once.
A = rand(16, 18);
B =[ 5 15;
7 5;
10 11;
11 13;
12 16;
14 9;
16 7]; %I'm guessing B(:,1) stores the rows to delete, B(:,2) stores columns to delete
A(B(:, 1), :) = [];
A(:, B(:, 2)) = [];
