Norm of block matrix
Web10 de abr. de 2024 · In addition, in contrast to the expectation y ∗, the variance matrix Q y ^ depends on the strength of the noise. Here, the trace of the matrix Q y ^ is the H 2 norm of the linear system where w (t) is seen as an input to the system. This H 2 norm is often used to analyze the fluctuations of the system subjected to disturbances. 13–15 13. B. K.

Webmatrix norms is that they should behave “well” with re-spect to matrix multiplication. Definition 4.3. A matrix norm on the space of square n×n matrices in M n(K), with K = R or K = C, is a norm on the vector space M n(K)withtheadditional property that AB≤AB, for all A,B ∈ M n(K). Since I2 = I,fromI ...
