7 Three non-singular square matrices, A, B and R are such that AR =B The matrix R represents a rotation about the z-axis through an angle 0 and-cos 0 sin0 0 B =sin0 cos0 00 0 17 (a) Show that A is independent of the value of 0.7(b) Give a full description of the ...
We restricted the matrices D2, D3,… to be diagonal in ‘AR’ models but not so in full vector autoregressive (‘VAR’) models. In both cases, we used LASSO regularization to promote sparsity in the regressors, signified by the ‘(sparse)’ suffix in method identifiers, with the ...

Let A and B be square nonsingular n-by-n matrices with entries being rational or rational Gaussian numbers. The paper describes a method for verifying whether these matrices are congruent. The method uses a finite number of arithmetic (and, in the complex case, also conjugation) operations....

Prove the following commutator identity: (AB, C) = A(B, C) + (A, C)B. Define and prove Bernoulli`s theorem. Prove Kirchhoff's current law. Prove {V_{f_A}-V_{f_B}/{V_{T_A}-V_{T_B}=-1 using the equations : (1) mA VA+mB V{BT}=mAV{Af}+mB V{Bf} ...
No smoothing was employed, complying with recent studies that report the negative influence of this procedure on the construction of connectivity matrices analysis. Moreover, a growing body of literature indicates the potential influence of participant motion inside the scanner on the subsequent ...
