WebIn the case of our toy model, f and g are two normal probability density functions, and θ p and θ o are vectors of parameters associated with each equation (i.e., θ p = β, σ p 2, θ o = α, σ o 2).Eq. 3 describes the autocorrelation in state values as a first-order Markov process, and Eq. 4 describes how observations depend simply on the states. WebThe State-Space block implements a system whose behavior you define as. x ˙ = A x + B u y = C x + D u x t = t 0 = x 0, where x is the state vector, u is the input vector, y is the output vector, and x 0 is the initial condition of the state vector. The A, B, C, and D matrices can be specified as either sparse matrices or dense matrices. normal ct chest sagittal
