用matlab创建矩阵的大学生基础

你好同学，给你生成5个

%1
A = ones(5,5);
A(2,:)=-1;A(:,2)=-1;A(2,2)=1; A = A+diag(0:5)
%2
A = ones(10) + diag(ones(10,1)*2020)
%3
A = diag(1:4) + diag(2:4,1)+diag(-2:-1:4,-1)
%4
format rat
A = 1./(1:11+(1:11)')
%5
A = zeros(4);
for i = 1:4
A(i,:) = circshift(1:4, [1,1-i]);
end
A

有帮助望采纳呢，谢谢啦
