How to split vectors
Web1. Using middle iterator A simple solution is to create two empty vectors and consider an iterator pointing to the vector’s middle element. Then the idea is to traverse the vector using iterators, and for each element, we check if it appears before the middle element or after the middle element in the vector. WebMar 24, 2024 · I'm reading Strang's Introduction to Linear Algebra, and cannot get why I can split every vector into a row vector and a null space vector. In fact, I don't why the book suddenly comes to this ... This means that X can be split into two vectors, one of row space of A and another of the null space of A. $\endgroup$ – Nicholas Humphrey.
