In this video I start to discuss the idea of the null space of a matrix. In these situations, the right-hand side of all the equations in the linear system is equal to zero. There is the trivial solution, where all the elements of the solution is zero. We are more interested in the spec

Null space of a matrix example
In today's lecture I work through an example to show you a well-known pitfall when it comes to the null space of a matrix. In the example I show you how to create the special cases and how to use them to represent the null space. There is also a quick look at the NullSpace function in Ma

Null points and null lines | Universal Hyperbolic Geometry 12 | NJ Wildberger
Null points and null lines are central in universal hyperbolic geometry. By definition a null point is just a point which lies on its dual line, and dually a null line is just a line which passes through its dual point. We extend the rational parametrization of the unit circle to the proj

In this video we finish with three more example of calculating the null space of a matrix. These three example help us gain an even deeper insight into the null space by consider how many special cases we will get. Remember that the linear combinations of the special cases give us the nu

Proof of the Rank-Nullity Theorem, one of the cornerstones of linear algebra. Intuitively, it says that the rank and the nullity of a linear transformation are related: the more vectors T sends to 0, the smaller its range. The proof is especially elegant and uses important concepts in line

Null space of a matrix using sympy
In this video I give a brief overview of the null space of a matrix and how to calculate (y hand) the column vectors that will make up the null space of the column. This becomes much easier in sympy, by simply using the nullspace function. If you want to learn more about the null space o

C: Pointer arithmetic and the call stack
In this video I show examples of pointer arithmetic. In particular, C strings (which are just arrays of chars). I also briefly go over the C call stack and show an example of a function being called.

C Programming: More string functions
Let's learn how a few more string functions work: trim newline, substring search. Plus: returning pointers instead of an index. Finally, we'll answer questions about the CSI assignment.

Null Space and Column Space of a Matrix
Given a matrix A(ie a linear transformation) there are several important related subspaces. In this video we investigate the Nullspace of A and the column space of A. The null space is the vectors that are "killed" by the transformation - ie sent to zero. The column space will be the image
