"NettetIn physics, a homogeneous material or system has the same properties at every point; it is uniform without irregularities. [1] [2] A uniform electric field (which has the same strength and the same direction at each point) would be compatible with homogeneity (all points experience the same physics).

Nettet29. jun. 2015 · I understand the two terms as follows: Homogenous solution - if x + y = b, then any ax + ay = b is also true, for any real number, except perhaps zero (if b is nonzero). Particular solution - any specific solution to the system. The question from the book: Suppose that MX=V is a linear system, for some matrix M and some vector V. Nettet9. mar. 2024 · If the homogeneous system A x = 0 has a solution, k x is also a solution, hence there is an infinity of them. If A x = b has a solution, let x 1, then A ( x − x 1) = 0, and if x 2 is also a solution, k ( x 2 − x 1) are solutions of the homogeneous system.

The fastest way to obtain the nullspace of a general matrix with eigen is by using its LU decomposition. In praxis I'm using the Householder QR decomposition instead of LU, because it appears to be more stable when the input matrix isn't perfectly singular. QR is still alot faster than the SVD proposed in the question and …
