Answer 1

[KALYAN ACHARJYA]

original_mat(1:17,:)=[];
original_mat(:,1:17)=[];

In the following example I have deleted 1 to 2 rows and columns of 5x5 matrics

original_mat=randi(10,[5,5])
original_mat(1:2,:)=[];
original_mat(:,1:2)=[];
original_mat

Results:

original_mat =
     9     7    10     5     8
     7     6     6     4     9
     3     2     1     8     4
     4     2     1     4     7
     2     5     9     6    10
     
original_mat =
     1     8     4
     1     4     7
     9     6    10
