matlab 矩阵编程问题

Question

如题所述

Answer 1

y
=
[1:30];
%给出y
x
=
[0:2]';
%给出x
yTanspose
=
zeros(3,
10);
%定义划分并转置后的存储矩阵
for
i
=
1
:
10

yTranspos(:,
i)
=
(y(3*i-2,
3i))';
%将y按每3个一组进行划分，并进行转置
end
xcord
=
[1:10];
%用于画图的x坐标
yNorm
=
xcord;
%用于画图的矩阵模
for
i
=
1
:
10

yNorm(i)
=
norm(yTranspos(:,
i)
-
x);
%求划分后的子向量与x的差的模
end
plot(xcord,
yNorm);
