How Can I delete specific elements in a matrix(rectangle matrix) and transfer them to other variable?
For example:
A=[1 2 3 4;
1 8 9 10;
11 12 20 6] ;
Suppose I want to delete 10 and 6, with out specifying element wise is there any way that i can delete the elements? Since my matrix is huge(24x15 elements) I can't specify element wise. I can only specify which row and which column.
Is there any technique that works efficiently?

A=[1 2 3 4;
1 8 9 10;
11 12 20 6] ;
You can't delete any element from your matrix. You can delete an entire column or an entire row.
You can find the position of your number 6 and 10 in your matrix
[ii,jj]=find(ismember(A,[6 10]))
a 24x15 array is not a huge matrix!

A=[1 2 3 4;
1 8 9 10;
11 12 20 6] ;
idx=ismember(A,[6 10]) % logical indices
A(idx)=0
