This article proves that let f be a transcendental entire function and k, n be positive integers, and let be an arbitrary meromorphic function satisfying T(r, c(z)) = S(r, f ) as . If , then the function f n (z) f ( k )(z) c(z) has infinitely many zeros, where = 0 if...

We establish the location of the zeros of several classes of 3 F 2 hypergeometric polynomials that admit representations as various kinds of products involving 2 F 1 polynomials. We categorise the 3 F 2 polynomials considered here according to whether they are well-poised or k-bal...
1、strncpy Copies the fifirst num characters of source to destination. If the end of the source C string (which is signaled by a null-character) is found before num characters have been copied, destination is padded with zeros until a total of num characters have been written to it. 拷贝...

使用程序2-5测试了图1-1中的全部明文图像,为了节省篇幅,这里仅给出图1-1(a)、(e)、(f)的测试结果,如图2-9所示。图2-9中的密钥使用了key=[125,75,220,190,88,246,195,78];,即用该语句替换程序2-5中的第3行。测试全黑图像或全白图像时,使用P=zeros(256,256);或P=ones(256,256)∗255;替换...
