Matlab 2D plotting by using given points

my x coordinates are from 0 to 30, and my y coordinates are

y=[0.74,0,71,0.68,0.64,0.59,0.53,0.48,0.42,0.35,0.29,0.21,0.17,0.11,0.065,0.047,0.016,0.0066,0.0026,0.0010,0.0002,0,0,0,0,0,0,0,0,0,0];

how to plot the graph so that when x=0, y=0.74 so on

Caution: you had 0,71 instead of 0.71

y=[0.74,0.71,0.68,0.64,0.59,0.53,0.48,0.42,0.35,0.29,0.21,0.17,0.11,0.065,0.047,0.016,0.0066,0.0026,0.0010,0.0002,0,0,0,0,0,0,0,0,0,0];
plot(0:length(y)-1, y)
