An Introduction to Numerical Analysis for Electrical and Computer Engineers

An improved symmetric SOR iterative method for augmented systems

“…Nevertheless, the number of iterations is greater that of the other two methods. We believe that a catastrophic cancelation [18] has been occurred here. Since, in both cases the optimal relaxation parameter is almost equal to 1.…”

Image deblurring using a perturbation-based regularization approach

“…Note that since f (γ) is differentiable and its derivative f (γ) can be easily obtained, one can use Newton's method [14] to obtain the root. The method can be applied by setting an initial value γ k=0 , where k denotes the iteration number.…”

“…In the numerical analysis, the Chebyshev nodes are the roots of the Chebyshev polynomial of the first kind. They are often used as nodes in polynomial interpolation because the resulting interpolation polynomial minimizes the problems of Runge's phenomenon [8]. For a given n, the n Chebyshev nodes are Polynomial interpolation is the interpolation of a given data set by a polynomial.…”
