If it helps to explain, I already understand the process of finding the basis of a column space and row space. I also understand why elementary row operations do not alter the null space of a …

Apr 29, 2018 · This answer explains what is null space very effectively. In brief Null Space is the set of vectors which have 0 effect on the system when applied. So, what is the use of finding …

The conclusion is that the full SVD provides an orthonormal span for not only the two null spaces, but also both range spaces. Example Since there is some misunderstanding in the original …

Sep 14, 2019 · In one of 3Blue1Brown's videos on linear algebra, he states that when a space such as a 2d plane is mapped to a line, a line of vectors in the plane is squished to a point, …

The null space is usually defined for a linear function, not for a set of vectors. You can, nonetheless, put those vectors together and make up a linear function.

Nov 28, 2016 · I can understand the dimension of column space of matrix is the no. of independent column vectors But why is the dimension of nullspace = no. of free variables?

The terminology "kernel" and "nullspace" refer to the same concept, in the context of vector spaces and linear transformations. It is more common in the literature to use the word …

Aug 24, 2021 · One way to find the dimension of the null space of a matrix is to find a basis for the null space. The number of vectors in this basis is the dimension of the null space.
