MATLAB 画图 y轴数值更改

Question

求解答，我怎么把这两个图弄到一起，两个图的x轴数值不一样，都是1到10 的范围，但是范围内取得点的个数不一样，图就差很多。

x = linspace(1,10,100000);
t = linspace(1,10,80);
z = sin((pipower(x,2))/4);
y = sin((pipower(t,2))/4);
subplot(1,2,1);plot(z);
subplot(1,2,2);stem(y);
subplot(1,2,2);stem(y,'r');

Answer 1

x = linspace(1,10,100000);
t = linspace(1,10,80);
z = sin((pi.*power(x,2))./4);
y = sin((pi.*power(t,2))./4);

hold on
plot(x,z);
stem(t,y,'r');
