ZERO BIAS - scores, article reviews, protocol conditions and more In the present paper, we extend the matrix inversion lemma in (1) to the case when the matrix above condition for the ranges of the relevant matrices, and present is positive semidefinite without the a matrix pseudo-inversion lemma. Such a singular case may occur in a situation where a problem dealt with is overdetermined in the sense that it 矩阵求逆引理(Matrix inversion lemma),通过分块矩阵求逆的方法证明:(A - C B^inv C')^inv = A^inv - A^inv C (B - C' A^inv C)^inv C' A^inv The utility of the Matrix Inversion Lemma has been well-exploited for several questions on MO. Thus, with some positive hope, I'd like to field a question of my own. In this article we show how these inversions can be computed non-iteratively in the domain using the matrix inversion lemma. This greatly speeds up computation and makes convolutional sparse coding computationally feasible even for large problems. The matrix inversion lemma to speed up the convolutional sparse coding was already independently used in recent papers B. Wohlberg, "Efficient Convolutional Sparse Coding", 2014, F. Heide, W. Heidrich, G. Wetzstein, "Fast and flexible convolutional sparse coding", 2015 and B.

Let , , and be non-singular square matrices; then General Formula: Matrix Inversion in Block form. Abstract: A generalized form of the matrix inversion lemma is shown which allows particular forms of this lemma to be derived simply. The relationships between this direct method for solving linear matrix equations, lower-diagonal-upper decomposition, and iterative methods such as point-Jacobi and Hotelling's method are established.
