Abstract: A method of generating a multivariable positive real function (MPRF) from the given multivariable real part is presented. The constraints on the given real part, in addition to its ...

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 ...

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 ...

In the last section, we talked about how we to think about moving along a 3-d cost curve. We know that moving along the 3-d cost curve above, means changing the $m ...
