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. Web3 de jan. de 2024 · I have a vector of integers and I want to construct a diagonal matrix with vectos's element as diagonal entries of the matrix. For example: if vector is 1 2 3 the diagonal matrix would be: 1 0 0 0 2 0 0 0 3 The naive way to do it would be just iterate over it and set elements one by one. Is there no other direct way to do this in eigen.
