A formula for various generalized inverses of a partitioned complex matrix is established under certain general conditions. The use of this formula in obtaining the Moore-Penrose inverse of an ...

Helper function MatInverseUpperTri () is used to compute the inverse of the R matrix that results from QR decomposition. The technique used to compute the inverse of an upper triangular or lower ...

where matrix is a numeric matrix or literal. The GINV function creates the Moore-Penrose generalized inverse of matrix. This inverse, known as the four-condition inverse, has these properties ...

We introduce a new sparse sliced inverse regression estimator called Cholesky matrix penalization, and its adaptive version, for achieving sparsity when estimating the dimensions of a central subspace ...

Because the inverse function is implemented from scratch, you'll be able to modify it in many ways to meet your own needs. For example, you might want to also return the absolute value of the ...
