Comparative numerical analysis to determine the weight of industrial warehouses
Abstract
Through this article, an investigation about the application of numerical analysis to structural calculations is carried out based on a sample, in which some metrics that describe its behavior are determined, such as its weight, with these values a polynomial is obtained that describes the represented model on a curve, which can be obtained through interpolation or regression. To obtain the polynomial by interpolation, the numerical methods of: Newton's divided differences, Lagrange and tracers or splines were applied, they were graphed independently, then they were grouped to analyze their behavior. With the regression, the least-squares method was applied to obtain the polynomial and represent its curve. With all the polynomials obtained, all their curves were drawn, consolidating them in a single graph, in which the most recommended category and method of numerical analysis is detailed, taking into account the mistakes found.
