矩阵乘法中的分段错误 [英] Segmentation fault in Matrix Multiplication
问题描述
大家好，
我在C中有一个矩阵乘法程序，它乘以两个
矩阵。
当它们的尺寸为3 * 3或800 * 800时，程序运行正常。但是在这个尺寸之上，我得到了一个分段错误。
我需要这个巨大的尺寸作为我的任务的一部分。
谁能告诉我出了什么问题？
谢谢。
Hi Guys,
I have a matrix multiplication program in C that multiplies two
matrices.
When their size is 3*3 or 800*800, the program runs fine. But above
that size, I get a "segmentation fault".
I need this huge size as part of my assignment.
Can anyone tell me what''s going wrong?
Thanks.

你的程序中有一个错误。
这可能是错误的 - 在第17行使用商店。

There''s a bug in your program.
It''s probably the mis-use of store on line 17.

Chris，
感谢您的回复。
但我是想知道你在哪里看到我的代码。我没有发布它。
谢谢
Chris,
Thanks for your reply.
But I was wondering where you saw my code. I didn''t post it.

他跟进了暗示使用ESP猜测的建议
你做了什么。你不可能在内存耗尽的情况下做任何事情，而不是在malloc（）中检查是否成功，或者你是否b / b
让我们看到它。
He was following up on your implied suggestion of use of ESP to guess
what you have done. You couldn''t have done anything along the lines of
running out of memory and not checking for success in malloc(), or you
would have let us see it.
