Matrix Equation: An equation in which the unknown variable is a matrix, frequently arising in systems theory and stochastic modelling to represent relationships between state transitions.

Solving systems of nonlinear equations can be challenging and analysts are often required to provide an initial guess of the solution as a starting point for use in an iterative solver. Insight into ...

This paper introduces an alternative method for analysing mathematical models by combining an artificial neural network (ANN) with a modified Levenberg-Marquardt (LM) optimization approach to solve ...

MP-Opt-Model is a package of MATLAB/Octave M-files for constructing and solving mathematical programming and optimization problems. It provides an easy-to-use, object-oriented interface for building ...

In two-dimensional XLOOKUP formulas, it doesn't matter which way around the XLOOKUPs go. In this example, the ID lookup is first in the formula, and the column header lookup is nested. If these were ...

If you’re someone who enjoys giving your brain a workout with puzzles and riddles, a new brain teaser might just be your next challenge. Shared by a Facebook user named Arshdeep Soni, the teaser ...

Abstract This paper focuses on the analytic and numerical dissipativity of θ-method for delay differential equations with a bounded variable lag. A generalized Halanay inequality is derived, and a ...
