Question

我有一个matlab函数，我从命令行调用：

matlab -nodisplay -nojvm -nosplash -nodesktop -r "matrix(10,'test')"

其中matrix.m包含以下内容：

function y=matrix(N,name)

A = randn(N);
[Q, R] = qr(A);

clearvars A R

ind = randperm(N);
indMinus = ind(1:round(N/2));

diagonal = ones(1,N);
diagonal(indMinus) = -1;

L = diag(diagonal);

mt = Q*L*(Q');

clearvars Q L 

fname = ['matrix',name,'.dat'];

fid = fopen(fname, 'w');
fprintf(fid,'%g\n',N);
for i=1:N
    for j=1:N
    fprintf(fid,'%g\n',mt(i,j));
    end
end

quit

当我运行此命令时，matlab无法完全启动，并陷入此状态：

$     matlab -nodisplay -nojvm -nosplash -nodesktop -r "matrix(10,'test')"

                                                   < M A T L A B (R) >

奇怪的是，这不是一个小时前发生的。我没有以任何方式更改代码。有足够的系统内存。当我运行以下代码时：

matlab -nodisplay -nojvm -nosplash -nodesktop

它正确启动了matlab：

$ matlab -nodisplay -nojvm -nosplash -nodesktop 

                                                   < M A T L A B (R) >

可能是什么问题？

从命令行运行时，Matlab脚本会卡住
