Warning: Matrix is singular to working precision.
程序是这样的
A=zeros(8);b=zeros(8,1);c=[];
for j=1:7;
A(j,1)=j/7;
A(j,2)=-1;
A(end,3:end)=1;
b(8,1)=78.36969;
end
c=A\b
要怎么解决?出现了 Matrix is singular to working precision.
MATLAB程序
这说明你在求矩阵时,产生奇异了,我想是你取值太靠近了,这样很容易产生奇异值
你看看你的Z：
Z =
NaN NaN NaN NaN NaN NaN -Inf
NaN NaN NaN NaN NaN NaN -Inf
NaN NaN NaN NaN NaN NaN -Inf
NaN NaN NaN NaN NaN NaN -Inf
NaN NaN NaN NaN NaN NaN -Inf
NaN NaN NaN NaN NaN NaN -Inf
NaN NaN NaN NaN NaN NaN -Inf
把这句改了一下也还是不行,显示矩阵的秩为1,y=0.9:0.1:1.2;
是你取的值太靠近了.
再问： 还会在线吗？我现在在写程序，如果不会能再问你吗？
Warning: Matrix is singular to working precision. matlab中Warning:Matrix is singular to working precision.是什么错误 用matlab画z的图.怎么提示Warning: Matrix is singular to working preci matlab求10阶线性方程出现Warning:Matrix is singular to working precis 请问在经济数学中 singular matrix是什么意思, singular matlab错误：Warning:Matrix dimensions must agree,not rendering is used to working啥意思? 这个What is the Matrix? To observe the past is to take the warning .怎么翻译啊?observe1.观 求翻译,to observe the past is to take warning for the future.i matrix
