... random distribution on the interval [0, 1). The recursive routine is found to be up to 2.5 times faster than sqrtm and 2 times faster than fort point. An extension of the Schur method due to Higham [10] enables the square root of a real matrix to be computed without using complex arithmetic. A real ...

Introduction to Linear Algebra using MATLAB Tutorial
... Two matrices are said to be equal to each other if they have the same dimensions, and all corresponding elements are equal. In MATLAB, there is a function isequal that will receive two matrix arguments and will return logical 1 for true if they are equal, or logical 0 for false if not. A matrix is s ...

... There is a substantial literature on the spectra of Toeplitz matrices and Toeplitz matrices with perturbations, and how they behave as N → ∞. For a review of this topic, see [1,2,7]. These references present the topic in a much more general setting than ours, but their focus is different from ours. ...

... The Range of T is spanned by (1,2,3), (2,3,4), (4,6,8). Since however (4,6,8) is a multiple of (2,3,4) it does not contribute any extra vectors to the Range of T from those spanned by (1,2,3) and (2,3,4). Thus the Range of T is as before in the last question. –x + 2y – z = 0. Its Rank is 2. From The ...
