上面的代码实现了一个目的――检查信号imf1（一个向量）是否存在绝对值大于1的点，这显然是基于C＋＋的思想写出来的。如果在matlab下面，其实用两个语句就足够了（当然，可以合并为一个）：-The above code implements a purpose- check signal imf1 (a vector) is greater than the absolute value of a point of presence, which is obviously based on C++ to write out the idea. If matlab below, in fact, enough with the two statements (of course, can be combined into one):
