用matlab 将一组数据进行正态分布拟合

x=[-2,-1.7,-1.4,-1.1,-0.8,-0.5,-0.2,0.1,0.4,0.7,1.0,1.3,1.6,1.9,2.2,2.5,2.8,3.1,3.4,3.7,4.0,4.3,4.6,4.9];
y=[0.10289,0.11741,0.13158,0.14483,0.15656,0.16622,0.17332,0.17750,0.17853,0.17635,0.17109,0.16302,0.15255,0.14020,0.12655,0.11219,0.09768,0.08353,0.07015,0.05876,0.04687,0.03729,0.02914,0.02236];

用matlab 对一组数据进行正态分布拟合 ，可以用nlinfit（）函数拟合得到其正态分布参数，
