The scaling produced by equilibrate is known as Hungarian scaling, and its computation involves solving a linear assignment problem. Get installers and licenses, renew existing licenses, learn with lots of online tutorials, and get support. See, for example, the recent paper Max-Balanced Hungarian Scalings by Hook, Pestana, Tisseur, and Hogg. MATLAB is a high-performance language for technical computing, integrating computation, visualisation, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. This matrix equilibration can improve conditioning and can be a useful preprocessing step both in computing incomplete LU preconditioners and in iterative solvers.

you have MATLAB R2019b Update 1 and your installator is MATLAB R2019b, no update), than, you cannot install the other toolboxes you could have access to. We have an extensive suite of test codes that we run to verify this, plus several of us here at Eigenvector always use the MATLAB pre-release in order to identify any issues. Release 2019b offers hundreds of new and updated features and functions in MATLAB and Simulink, along with two new products. MathWorks today introduced Release 2019b with a range of new capabilities in MATLAB and Simulink, including those in support of artificial intelligence, deep learning and the automotive industry. If the installator you have got from your IT has no update but you have installed an update (e.g. As far as compatibility updates go this was a fairly easy one: the changes from MATLAB 2019a to 2019b didn’t break any of our code. The equilibrate function take as input a matrix A (dense or sparse) and returns a permutation matrix P and nonsingular diagonal matrices R and C such that R*P*A*C has diagonal entries of magnitude 1 and off-diagonal entries of magnitude at most 1. The reason is that, nowadays there are 'MATLAB Updates' for a given version (e.g.

This problem can also be described as finding a minimum-weight matching in a weighted bipartite graph. The matchpairs function solves the linear assignment problem, which requires each row of a matrix to be assigned to a column in such a way that the total cost of the assignments (given by the “sum of assigned elements” of the matrix) is minimized (or maximized).
