How to select different indices for each column in an array

I am currently start with an array

xOn = zeros(4,2)

and index matrix

xInd = [1,3;2,4];

I am executing the command

xOn((xInd(1,:):xInd(2,:)),:) = 1;

with the goal of getting xOn that looks like

1 0

1 0

0 1

0 1

Instead, xOn=

1 1

1 1

0 0

0 0

Is there a way to get the first result?
