How do I replace Matrix elements

Given a matrix A replace elements not equal 0 and not equal 1 by 5. Use disp() function to print out the resulting array.

So far I've got

A(A~=0) = 5;

disp(A);

but do not know how to make it 0 AND 1.

When you use ~=0 and replace those with 5, the elements whch have 1 also will be eplaced by 5 right?

Yeah so all elements that don't = 1 or 0 need to be replaced by the element 5

Try this:

A((A>1)|(A<0))=5

But here is a question why you would like to do this operation? At the last you know all the elements will be '5' in result if need to use both the conditions.

Oh no, so I want to replace all elements that don't equal 1 or 0. So the array should be made up of 0's 1's and 5's like so...

A = [-1 0 4 6; 1 1 0 2; -7 0 5 0; 5 1 5 1];

would become

A = [5 0 5 5 1 1 0 5 5 0 5 0 5 1 5 1]

[Sudhakar Shinde]

Then you can simply use:

A((A>1)|(A<0))=5

Use AND instead of OR:

>> A = [-1,0,4,6;1,1,0,2;-7,0,5,0;5,1,5,1]
A =
  -1   0   4   6
   1   1   0   2
  -7   0   5   0
   5   1   5   1
>> A(A~=0&A~=1) = 5
A =
   5   0   5   5
   1   1   0   5
   5   0   5   0
   5   1   5   1
