Question

 i have a matrix is A.The size of matrix of A is 16*18.
The matrix B=[ 5    15;
     7     5;
    10    11;
    11    13;

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 .

Answer 1

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)) = [];
