Discard rows and columns from a matrix that exclusively contain zero-valued off-diagonal matrix elementsUwe Menzel
where\(\Sigma \)is a diagonal matrix of ordernwith nonzero real entries,\({\mathcal {Q}}(x)\)is an\(n\times n\)matrix potential anticommuting with\(\Sigma \)with its entries belonging to\(L^1({\mathbb {R}})\)and\(x\in {\mathbb {R}}\)is position, has been studied at g...
I have a square matrix and would like to make the diagonal elements zero, as well as select elements that are off-diagonal. For the latter, I only want the elements next to (one removed from) the diagonal to be zero, e.g., I would want A(5,6) and A(6,5)...
Diagonal elements, specified as a scalar, vector, or matrix. This argument is typically (but not necessarily) full.spdiagsuses the columns ofBinto replace specified diagonals inA. If the requested size of the output ism-by-nandBinis a column vector or matrix, thenBinmust have at leastmin(m,...
Ran in: Simple is to use diag. n = 5;% Now many non-zero elements will we have? N = 1:(2*n);% a simple index vector D = N.*mod(N-1,2);% create the elements of the main diagonal A = diag(D) A =10x10 0 0 0 0 0 0 0 0 0 ...

For instance, the first column of Fig. 6(a) is generated when we optimize over bangs for the mustache classifier. We record the CLIP prediction variation. It clearly shows that bangs is the dominant attribute changing during the optimization. From the main diagonal of matrices, it is evident...
