Abstract: The coprime planar array (CPPA) can obtain a larger virtual aperture using the sum-difference co-array (SDCA). Nonetheless, the holes in the SDCA always cause the virtual aperture to be not ...

The winning numbers in Tuesday's drawing of the "North Carolina Cash 5 Double Play" game were: 7, 18, 28, 30, 33 ...

The demo defines a matrix as an array of arrays of type double. It's possible to use a program-defined matrix class, but in my opinion this approach creates unnecessary complexity.

Abstract We consider dimension reduction for regression or classification in which the predictors are matrix- or array-valued. This type of predictor arises when measurements are obtained for each ...

What is the prefix sum array problem? The prefix sum problem in computer science is a popular programming puzzle used to test the array handling skills of software developers. The prefix sum problem ...

If the source matrix is a covariance matrix, then using Cholesky decomposition is efficient. The implementation of QR-Householder matrix inverse presented in this article emphasizes simplicity and ...

Use array interface for CSC matrix and align the interface with CSR and dense. - Fix nthread issue in the R package DMatrix. - Unify the behavior of handling `missing` with other inputs. - Unify the ...

Sparse linear arrays based on a novel subarrayed scheme are proposed and synthesized in this letter. The array with a fixed aperture size is partitioned into several uniformly spaced subarrays while ...

Microsoft Excel's new FILTER() function is a great tool for reporting and dashboards. We'll show you how to use it to get more done.
