MATLAB 用for循环给数组赋值的问题

要实现对x(1)到x(21)赋值，我代码如下：
for u=0:0.05:1
i=u*20+1;
x(i)=x0+x1*power(u,2)+x2*power(u,3)+x3*power(u,3)+x4*power(u,4)+x5*power(u,5);
end

结果报错：
In an assignment A(I) = B, the number of elements in B and I must be the same.

X0、X1、X2、X3、X4、X5是普通的参数，请问我该如何修改？

Answer 1

x0=2;x1=2;x2=8;x3=3;x4=5;x5=4;%--------假设的值
for i=1:21
u=0:0.05:1;
x(i)=x0+x1*power(u(i),2)+x2*power(u(i),3)+x3*power(u(i),3)+x4*power(u(i),4)+x5*power(u(i),5);
end
