发帖数: 156 | 2 My sub-program needs quite some editing for the specific task, so I chose to
use %include instead of macro.
The example I got from internet is like
filename project "folder_directory";
%include project(subprogram);
But I found when the main program was the same folder, codes like the below
one also worked. Is there any pitfall I did not refer to folder directory?
%include subprogram;
Thanks in advance. |

发帖数: 722 | 4 No, it is impossible to solve this problem by dynamic programming because
this problem doesn't exhibit optimal substructure.
For example, postage of 8 cents is a subprogram of postage of 16 cents. But
the optimal solution for 8 cents is just one 8 cents stamp, which is not
part of the optimal solution for postage of 16 cents.
I guess this problem is NPC. |

发帖数: 29 | 7 如果商业软件使用 shared libraries and dynamically linked subprograms ，应该提交他的全部代码？
GPLv3 比GPLv2哪个更严格？ 看了很头晕。有没有涉及GPL v3 的案例？ |

看到的几个题，像请教下大家。
谢谢啦。
1.Write an 8086 procedure which will accept three 16-bit integer arguments (
passed on the stack) and will return their sum in the AX register.
我写的答案是：
push bp
mov bp,sp
mov ax,[bp+4]
add ax,[bp+6]
pop bp
ret 4
问问大家这个对吗？
还有两个题。
2.Write an 8086 procedure which will receive a 16-bit integer as input
parameter on the stack, swaps the high byte and low byte of the word, and
return the new value in ax。
3.Write an 8086 subprogram that is passe... 阅读全帖 |

pta = &a[0]; // why wrong? How to correct?
subprogram(pta); |

发帖数: 255 | 10 Thanks so much!
My problem is that subprogram(pta) is a third-part program that only
accepts a double pointer **pta. How can we do to match it? |

发帖数: 167 | 11 Just wrote a subprogram to output data from my MPI(F90) code. Then I found
that the data is not in ASCII format. Is there anyway that I can transform the
data file so that it is readable from Matlab? |
