为何会出现如下错误?

1. Send this crash report to segv@mathworks.com for automated analysis.
   For your convenience, this information has been recorded in:
       C:\DOCUME~1\donglx\LOCALS~1\Temp\matlab_crash_dump.3188
2. Also, if the problem is reproducible, send the crash report to
   support@mathworks.com along with:
       - A specific list of steps that will reproduce the problem
       - Any M, MEX, MDL or other files required to reproduce the probl
em

Error in ==> E:\导出ANSYS模型的质量和刚度矩阵\cm.m
On line 8==> save k.txt K -ascii


程序如下:
clear all
load E:\导出ANSYS模型的质量和刚度矩阵\filestiffness.txt;
K=sparse(8922,8922);
for n=1:89103
    K(filestiffness(n,1),filestiffness(n,2))=filestiffness(n,3);
end
clear filestiffness
save K.txt K -ascii


如果把K=sparse(8922,8922)去掉,就不会错了.但是如果去掉了会在运行一段时间后:out of memory

load E:\导出ANSYS模型的质量和刚度矩阵\filestiffness.txt;可能出错在这

filestiffness.txt; 最好放到 你允许程序的根目录下。

恩，而且最好不要使用中文路径

clear all
load filestiffness.txt;
K=sparse(8922,8922);
for n=1:89103
    K(filestiffness(n,1),filestiffness(n,2))=filestiffness(n,3);
end
clear filestiffness
save K.txt K -ascii


改了之后情况依然存在!!!!       K矩阵已经生成,就是不能保存.

去掉SAVE那一行命令后我对K求值,det(K),得到的是NaN,为什么?

估计是矩阵太大了，建议分批存储吧
