How to generate a 2-d impulse function δ(n1,n2) ?

As part of my miniproject work i have to generate a 2-D impulse function in matlab.The signal to be generated are δ(0, c∆Tsn2),δ(1,c∆Tsn2),δ(2,c∆Tsn2),δ(3,c∆Tsn2),δ(4,c∆Tsn2).........δ(N-1,c∆Tsn2),where c=velocity of light.∆Ts=13.33ns.How can i generate these signals.Can i approximate these signals as 1-D signals.Pls help me .
