Numpy is a python library for numerical computing. It provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays.

Abstract: This paper presents a randomized linear-dispersion space-time block code for decode-and-forward synchronous relays. The coding matrices are obtained as a set of columns (or rows) of randomly ...

Abstract: Sparse superposition codes were originally proposed as a capacity-achieving communication scheme over the gaussian channel, whose coding matrices were made of i.i.d. gaussian entries [1]. We ...

Iterate over all pairs of rows. When fixing two rows r1 and r2, we can convert this to 1D version of the problem. When we have a 1D array ARR we want to find number of subarrays such that the sum of ...

In recent years, there has been extensive research on sparse representation of vector-valued signals. In the matrix case, the data points are merely vectorized and treated as vectors thereafter (for ...
