matlab 不是这么用的

function question_37
clear;clc
syms x t
x=t/10+1;
tt=0;
for i=1:1:100
    xnew=subs(x,t,tt);
    xnew=vpa(xnew);
    xmatrix(i)=xnew;
    tt=tt+0.1;
end
plot(0:0.1:9.9,xmatrix)

使用嵌套函数，或者参考下面的例子。


function question_37
clear;clc
syms x t
x=t/10+1;
tt=0;
for i=1:1:100
    xnew=subs(x,t,tt);
    xnew=vpa(xnew);
    xmatrix(i)=xnew;
    tt=tt+0.1;
...
