Revision history:
1.0 (2 August 2002, do
ug Lake) Original version
1.1 (6 January 2004, George Moody) Removed limits on input series length
1.2 (1 November 2004, George Moody) Merged bug fixes from DL (normalize
by standard deviation, detect and
avoid divide by zero);
changed code to
use do
uble precision, to avoid loss of
precision for small m and large N
Compile this program using any standard C compiler, linking with the standard C
math library. For example, if your compiler is gcc, use:
gcc -o sampen -O sampen.c -lm
For brief instructions, use the '-h' option:
sampen -h

靠,连问都问的这么不成心,随便抓段代码就往这里放,问下你自己,你自己真想学吗?
 
我看是没有人这么有空帮你转换这么大段代码了,你还是先学好一点,自然就会转了。
 
短点可以考虑!
 
确实太长了,哎,心有余而时间不足,
算是也帮你顶一下,期待下一位朋友能帮你.
 
不会是C++的枪手吧,叫大家去学C++.
 
呵呵,本想帮着翻译的,打开一看,太长了!还是帮你顶吧!
 
不懂的路过,确实太长,而且搂住没有什么说明~~~
帮顶
 
你要提示:这是干什么的。让人先有个底。然后读代码就不费事了,
 
就是,好长啊……爱莫能助啊……,
 
楼主来挑衅的吧
 
要標明rmb的。。
