Two matrices A and B. B is subset of A(rowwise).I want to check the indexes for which row of B is there in A and do some operation on those indexes of A. I tried like this, works for small matrices but takes tim
Create the function mysigmoid.m , which accepts two matrices in the feature space as inputs, and transforms them into a Gram matrix using the sigmoid kernel. function G = mysigmoid(U,V) % Sigmoid kernel function with slope gamma and intercept c gamma = 1; c = -1; G = tanh(gamma*...
Calculate the QZ factorization and also return the generalized eigenvectors of two 2-by-2 matrices. Get A = [10 -7; -3 2]; B = [7 3; 12 9]; [AA,BB,Q,Z,V,W] = qz(A,B) AA = 2×2 11.9600 -4.3532 0 -0.0836 BB = 2×2 1.6381 -2.9374 0 16.4830 Q = 2×2 -0.9597...
Let A and B be 3 Times 3 matrices with det(A) = 2 and det(B) = 7. Find the value of: (a)det(AB) (b)det(2A) (c)det(3AB) (d)det(AB-1) If A and B are 4 by 4 matrices, det(A) = 2, det(B) = 4, find the foll...
Bibliometric analysis of a publication dataset; Building and plotting matrices for co-citation, coupling, collaboration, and co-word analysis. Matrices are the input data for performing network analysis, multiple correspondence analysis, and any other data reduction techniques. ...
Successful materials design for bone-tissue engineering requires an understanding of the composition and structure of native bone tissue, as well as appropriate selection of biomimetic natural or tunable synthetic materials (biomaterials), such as polymers, bioceramics, metals and composites. Scalable fabri...
It is in general faster than searching the full 6D parameter space directly since large parts of the rotation space may be unconditionally discarded, and since evaluating each bound is faster as features are only rotated once for the outer BnB. We extend upon this idea by proposing two ...
whereρ^is the relevant density matrix for the initial state, which is given by 1 for a scalar initial state. For a spin-$\frac{1}{2}$ state, the density matrix can be parameterised in terms of a polarisation vectorpiand the Pauli matricesσi, and is given by: ...
the individual estimates are subsequently summarized. Any conclusion about the overall sample would have to be inferred by summarizing thenestimates, for instance by calculating the average and the variance of the intercepts and of the slopes across all individuals. Note that the two steps are comput...
Machine learning plays an increasingly important role in many areas of chemistry and materials science, being used to predict materials properties, accelerate simulations, design new structures, and predict synthesis routes of new materials. Graph neural networks (GNNs) are one of the fastest growing ...
