WebAug 31, 2024 · The generalized Moore–Penrose inverse is defined from algebraic and geometrical point of view. Some equivalent conditions for a generalized Drazin invertible … In mathematics, and in particular linear algebra, the Moore–Penrose inverse $${\displaystyle A^{+}}$$ of a matrix $${\displaystyle A}$$ is the most widely known generalization of the inverse matrix. It was independently described by E. H. Moore in 1920, Arne Bjerhammar in 1951, and Roger Penrose in 1955. … See more For $${\displaystyle A\in \mathbb {k} ^{m\times n}}$$, a pseudoinverse of A is defined as a matrix $${\displaystyle A^{+}\in \mathbb {k} ^{n\times m}}$$ satisfying all of the following four criteria, known as the … See more Since for invertible matrices the pseudoinverse equals the usual inverse, only examples of non-invertible matrices are considered below. • See more Rank decomposition Let $${\displaystyle r\leq \min(m,n)}$$ denote the rank of $${\displaystyle A\in \mathbb {k} ^{m\times n}}$$. Then $${\displaystyle A}$$ can … See more Besides for matrices over real and complex numbers, the conditions hold for matrices over biquaternions, also called "complex quaternions". In order to solve more general least-squares problems, one can define Moore–Penrose … See more Existence and uniqueness The pseudoinverse exists and is unique: for any matrix $${\displaystyle A}$$, there is precisely one matrix $${\displaystyle A^{+}}$$, … See more Scalars It is also possible to define a pseudoinverse for scalars and vectors. This amounts to treating these as matrices. The … See more Linear least-squares The pseudoinverse provides a least squares solution to a system of linear equations.

The Moore-Penrose Pseudoinverse (Math 33A: Laub)
WebIn this case b is called the Moore-Penrose inverse of a, see [16] where this concept was introduced. In [10] it was proved that each regular element a in a C∗-algebra A has a uniquely determined Moore-Penrose inverse.
