The Octave programming language provides a pseudoinverse through the standard package function pinv and the pseudo_inverse() method. In Julia (programming language), the LinearAlgebra package of the standard library provides an implementation of the Moore–Penrose inverse pinv() … Visa mer 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 … Visa mer Since for invertible matrices the pseudoinverse equals the usual inverse, only examples of non-invertible matrices are considered below. • For Visa mer Scalars It is also possible to define a pseudoinverse for scalars and vectors. This amounts to … Visa mer Linear least-squares The pseudoinverse provides a least squares solution to a system of linear equations. … Visa mer 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 … Visa mer Existence and uniqueness The pseudoinverse exists and is unique: for any matrix $${\displaystyle A}$$, there is precisely one matrix $${\displaystyle A^{+}}$$, … Visa mer Rank decomposition Let $${\displaystyle r\leq \min(m,n)}$$ denote the rank of The QR method Visa mer WebbDie Pseudoinverse einer Matrix ist ein Begriff aus dem mathematischen Teilgebiet der linearen Algebra, der auch in der numerischen Mathematik eine wichtige Rolle spielt.

The only hypothesis we make on the rank of the matrix is that it must be locally constant at the point where the derivative is calculated.
