RANK atribuie același rang numerelor duplicate. Totuși, prezența numerelor duplicate afectează rangurile atribuite numerelor următoare. De exemplu, într-o listă de întregi sortați în ordine crescătoare, dacă numărul 10 apare de două ori și are rangul...
This line was then crossed into Rankflox/flox mice to examine Brca1 deletion-induced tumorigenesis in the presence or ab- sence of RANK expression (Supplementary information, Figures S1A, S1B and S2). All mouse lines examined appeared to develop normal mammary glands at puberty. In 4-month-...

Researchers in many fields use networks to represent interactions between entities in complex systems. To study the large-scale behavior of complex systems, it is useful to examine mesoscale structures in networks as building blocks that influence such b
This way you won't change your original array, but get a mapping from your array elements to its rank. Obviously this algorithm depends on the complexity of your sort algorithm. You should end up with O(n log n) but maybe your data allows to use sorting algorithms with O(n...
故A+B=AB=BA,(即A,B可交换), 从而B=A(A-I)^{-1}\Rightarrow \mathrm{rank}(B)\leq\...
1.对于矩阵A,B,如果AB=0,试证明:rank(A)+rank(B)≤n。 证明:令W为方程AX=0的解空间,那么dimW=n−rank(A),因为AB=0,因此B中的任意列向量βi都满足βi∈W(i=1,2,...,n),因此rank(B)≤dimW。故有r(A)+r(B)≤n。 2.(Sylvester不等式)对于矩阵An×n,Bn×n。试证明:rank(AB)≥rank(...
