Finding the extrema of a multivariable function is an essential skill in calculus and applied mathematics. This process allows you to determine the minima and maxima of a function across multiple ...

Introduction: The domain of a function is the set of all possible input values (x-values) for which the function is defined. Understanding the domain is crucial for solving mathematical problems and ...

Abstract: This paper describes how to find the extremum of a constrained multivariable function by taking advantage of its structure. Three steps lead to the solution. The first step discusses ...

Abstract: Estimation of the parametric multiple-input-multiple-output (MIMO) infinite impulse response transfer function given time-domain input-output (IO) data is considered. We first propose a ...
