[U,S,V] = svd (X) produces a diagonal matrix S of the same dimension as X, with nonnegative diagonal elements in decreasing order, and unitary matrices U and V so that X = U*S*V'. [U,S,V] = svd (X,0) produces the "economy size ...
WebOct 18, 2024 · Calculate Singular-Value Decomposition. The SVD can be calculated by calling the svd () function. The function takes a matrix and returns the U, Sigma and V^T elements. The Sigma diagonal matrix is returned as a vector of singular values. The V matrix is returned in a transposed form, e.g. V.T. WebThe optimization problem is given by: arg min x f ( x) = arg min x 1 2 ‖ h ∗ x − y ‖ 2 2. Where x is the data to be restored, h is the Blurring Kernel (Gaussian in this case) and y is the set of given measurements. The model assumes the measurements are given only for the valid part of the convolution.
