An Algorithm for Non-negative Leslie Matrices

The Leslie matrix plays a crucial role in analyzing the changes in survival and birth rates, thus determining the population’s evolution. However, when it comes to evaluating continuous solutions of population growth models, discrete solutions are necessary. The Leslie matrix model, being a discrete model based on the age stage of the population, becomes particularly relevant in this context. In this work, we present a computational mathematical tool designed be used in the Leslie matrix model, which consists of reconstructing a Leslie matrix of any order from a given set of real numbers.
