I have a matrix like:
A=[2 4 8 1 4 6]
I want to set everything to zero accept element 3-5.
The result should be
A=[0 0 8 1 4 0]
How can I do that?

A([1:3-1 5+1:end]) = 0

the question is to set everything to zero accept element 3-5. So +1 and -1 captures the elements beyond these limits. In this example, 1 to 2 and 6 to the last element.

A=[2 4 8 1 4 6] ;
B = zeros(size(A)) ;
B([3,5]) = A([3,5]) ;
