Question

这里我试图绘制错误（矩阵之间的归一化差异）与变量rho。所有其他变量应保持不变。我真正想做的是将rho存储为单独的向量，并在每个循环中计算错误时存储错误值。

有什么想法吗？

%Variables:
%MatrixGen.m:   p,q - matrix size, rho- percentage complete, r - rank
%NuclearNorm.m :   Zincomplete

clear

p=10; q=10;
r=2;

for rho=0.1:0.3:0.9;

    [Ztrue, Zincomplete] = MatrixGen(p,q,r,rho)

    tic
    [Zreconstructed] = NuclearNorm(Zincomplete)
    toc

    Error= norm(Ztrue-Zreconstructed, 'fro')

    hold on
    plot (rho, Error)

end

'那是你的意思吗？

%Variables:
%MatrixGen.m:   p,q - matrix size, rho- percentage complete, r - rank
%NuclearNorm.m :   Zincomplete

clear
p=10; q=10;
r=2;

rho = 0.1:0.3:0.9
errors = zeros(size(rho))

for i=1:length(rho);

    [Ztrue, Zincomplete] = MatrixGen(p,q,r,rho(i))

    tic
    [Zreconstructed] = NuclearNorm(Zincomplete)
    toc

    errors(i) = norm(Ztrue-Zreconstructed, 'fro')
end

plot(rho, errors)

end
