Since Donald Trump hit Xi Jinping’s government with punitive tariffs in 2018, his push to cut the trade deficit has snowballed into a full-scale bipartisan effort to stop China from becoming the world ...

Currently, I need to perform Gaussian filtering on images, but I want to avoid using MATLAB's built-in functions. Given an image of size N x N, my idea is to construct a sparse matrix where both ...

Abstract: Sparse arrays offer economic advantages by reducing the number of antennas. However, directly utilizing the covariance matrix of sparse array signals for wideband beamforming may lead to the ...

A new technical paper titled “Signal processing architecture for a trustworthy 77GHz MIMO Radar” was published by researchers at Fraunhofer FHR, Ruhr University Bochum, and Wavesense Dresden GmbH.

We audiophiles often say that our interest in gear is rooted in our love of music. That isn’t always truly the case, but in this instance, it is. My interest in the German pro-audio company Holoplot ...

Presenting an algorithm that solves linear systems with sparse coefficient matrices asymptotically faster than matrix multiplication for any ω > 2. Our algorithm can be viewed as an efficient, ...

News update: Donald Trump announced that he has selected J.D. Vance as his running mate. In May, Vance sat down for a long conversation with Ross Douthat, an Opinion columnist. In 2016, J.D. Vance’s ...

Is your feature request related to a problem? Please describe. I am not sure if I am doing something wrong but I am using scipy.sparse.csr_matrix object and contract it with a np.ndarray object using ...
