So, we can use range based for loops to fill it for (std::vector<int>& row : m.data) // Go over all rows for (int& col : row) // For each column in a row is >> col; // Read the value and put in matrix return is; } // Write matrix to any stream friend std::ostrea...
Given a binary matrix M∈{0,1}m×n, let |M| denote the number of 1 entries of M. Writing p=|M|mn, define the discrepancy of M as disc(M)=maxX⊂[m],Y⊂[n]||M[X×Y]|−p|X|⋅|Y||. Viewing M as the bipartite graph, whose vertex classes are the rows and columns...
‘). We can use the matrix transpose and multiplication operation to create a vector inner product in the following manner. Suppose w and v are m*1 vectors. Then the inner product ( also known as the dot product ) is given by w’*v. the inner product of two vectors is a 矩阵移置...

Note that idWλ corresponds to the tensor ∑i=1dλwi∗⊗wi, where dλ≔dimWλ and the sets of vectors {wi}i=1dλ and {wi∗}i=1dλ are bases of Wλ∗ and Wλ that are dual to each other. The above choices give a well-defined normalization of the operator Dλ. Indeed...
Transpose of a matrix: The matrix obtained by swapping its own rows and columns is called its transpose. Given a matrixAits transpose is denoted byAT. Determinant of a matrix: Corresponding to each matrix we can define a real number dependent on the entries and their corresponding position. ...
Testing for large-dimensional covariance matrix under differential privacy 摘要:The increasing prevalence of high-dimensional data across various applications has raised significant privacy concerns in statistical inference. In this paper, we propose a differentially private likelihood ratio statistic for testin...
The resonance arrangement An is the arrangement of hyperplanes which has all non-zero 0/1-vectors in Rn as normal vectors. It is the adjoint of the Braid arrangement and is also called the all-subsets arrangement. The first result of this article shows that any rational hyperplane arrangement...
