在Python中，使用for循环无法直接处理无穷区间，因为循环需要有一个终止条件。无穷区间是无限的，没有明确的终止点，因此无法使用传统的for循环语法来处理。然而，您可以通过一些技巧来模拟处理无穷区间的效果。例如，可以使用itertools.count()函数生成一个无限增加的计数器，并结合break语句来实现类似无穷区间...
Current algorithms identify double-stranded DNA regions, as well as single-stranded RNA regions that can form a triplex, but no programs are available to identify such regions in a structured RNA. We wrote TFOFinder, a Python program to design probes that are predic...

你尝试用一个int型的M作为除数，结果赋值给double型的real和imag，建议在M前加上（double）强制类型转换，即real=d_buffer[i][0]/(double)M;imag=d_buffer[i][1]/(double)M;最后的max=magnitude[0];magnitude明明是double型变量，不是数组 ...
