How Can I delete specific elements in a matrix and transfer them to other

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!

Thank you sir

and yeah 24x15 may not be a huge one, I have 49 such matrices which i forgot to mention and it's tedious to delete specific elements in every matrix

Thanks anyhow sir

If you have

A=[2 4 ; 5 44];

If you delete the number 5 from your matrix, what will be the result?

[Divya]

Yeah I got you Sir. I should not delete any element from a matrix

May be I should correct my question to -- how can i make specific elements to zero in a matrix

[Azzi Abdelmalek]

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

Thank you sir
