How to find the index in array?

Dear all,

I have the following array A = [0;0;0;0;0;0;1;1;;0;0;0;0];

I want to find the right and left index of the 1's? In this case

Left_A = 7

Right_A = 8

In another situations, A = [0;0;0;0;0;0;1;0;0;1;0;0;0];

Left_A = 7

Right_A = 10

Any idea how to do that? Thank you very much.

Left_A = find( A == 1, 1 );
Right_A = find( A == 1, 1, 'last' );

That works very well. Thank you very much.
