Dr. James McCaffrey from Microsoft Research presents a complete end-to-end demonstration of computing a matrix inverse using ...

There are special types of matrices with unique properties that are important for understanding how matrices can be applied in specific contexts, such as identity matrices in solving systems of linear ...

Here the first summand on the right-hand side comes from the estimate of the diagonal part of the decomposition of C ... to achieve by decomposing the off diagonal part of C into three matrices each ...

The terms horizontal, vertical, and diagonal spreads refer to the positions of each option on an options grid. Options are listed in a matrix of strike prices and expiration dates. Options used in ...

Now we define a new class called `Diag`, this class receive a container that can be the parameter of `std::data`, e.g `std::vector`, `std::initializer_list`. This class is for specify a diagonal ...

then its inverse matrix Ai is n-by-n and the matrix product of Ai * A is the n-by-n Identity matrix (1s on the upper-left to lower-right main diagonal, 0s off the diagonal). An analogy in ordinary ...

This paper proposes a novel shrinkage estimator for high-dimensional covariance matrices by extending the Oracle Approximating Shrinkage (OAS) of Chen et al. (2009) to target the diagonal elements of ...

Abstract: We present a technique to construct diagonal material matrices for arbitrary triangular and tetrahedral meshes and arbitrary scalar material parameters. The recipe is based on a novel dual ...

The trace and copysign implementation of matrix_to_quaternion means that gradients flow only on the main diagonal of the matrix, used to compute the trace. From what I understand of the axis-angle ...
