How to tell if two matrices are similar?Invertible Matrix:A Matrix is considered to be invertible if and only if its determinant is not zero. If the matrix has a determinant of zero, it is not possible to find an inverse.Answer and Explanation: ...
These beetles' life histories and the circadian rhythms of sexual behavior are very similar, and their emergence phenology overlaps widely (Xue HJ, personal observation); thus, temporal isolation is likely not an important isolating mechanism. Therefore, habitat isolation, beha- vioral isolation or ...
-- = Models did not converge due to non-positive definite variance–covariance matrices of the predictor variables. To deal with missing data due to study attrition, incomplete responses, and planned missing data by design, we applied the full information maximum likelihood (FIML) approach ...
an extensive number of eigenstates of a non-Hermitian Hamiltonian are localized at the end(s) of the chain. Here in two and higher dimensions, we establish a theorem that the skin effect exists, if and only if periodic-boundary spectrum of the Hamiltonian covers a ...
We show that U λ is a self-similar set satisfying the open set condition if and only if U λ can tile an interval by finitely many of its affine copies (admitting different dilations). Furthermore, each such λ can be characterized as the spectrum of an irreducible double word which ...
If A is a 3 x 3 matrix with eigenvalues of 1,1,-1, then A is not diagonalizable. True or false? True or False. Two square matrices A and B can have the same determinant if and only if they are of the same size. Let A and B be arbitrary 3 times 3 mat...
The zero-sequence self-reactancesX0(1,1),X0(2,2), and mutual reactanceX0(1,2) =X0(2,1) are also computed using similar equations. Extension from the following two (2x2) reactance matrices in positive-sequence and in zero-sequence ...
3.5. Correlation between LUCC and EF – ELIA The two methods would reveal similar or different results. Hence, we consider how their similarities and differences deal with the LUCC at spatial level. For this propose the standard values of the two methods in each municipality were subtracted, and...

Select the effective SCs that are similar to the original signal. It is proposed to use a correntropy induced metric (CIM) to express the similarity between SCs and the original signal. For variables X and 𝑌Y, define CIM as (7): CIM(𝑋,𝑌)=[𝑘𝜎(0)−𝑉(𝑋,𝑌)]1/...
