Benefits of MATLAB for Mathematical Modelling

MATLAB (short for MATrix LABoratory) is a high-level programming environment and numerical computing platform developed by MathWorks. It is widely used for technical computing, data visualization, algorithm development, and numerical analysis. MATLAB combines an easy-to-use interface with powerful computational capabilities, making it popular among engineers, scientists, and researchers. Its extensive library of built-in functions and toolboxes allows users to perform complex mathematical operations, simulate systems, and analyze data efficiently. MATLAB is particularly suited for matrix manipulations, solving equations, and implementing advanced algorithms in various fields.

Overview of Mathematical Modelling / Analysis
Mathematical modelling involves using mathematical equations and expressions to represent real-world systems or phenomena. It provides a framework for understanding complex systems by simulating their behaviour under different conditions. These models are essential in predicting outcomes, optimizing processes, and solving problems across disciplines such as physics, biology, economics, and engineering. 

Mathematical analysis complements modelling by evaluating the properties of these models - such as stability, sensitivity, or accuracy - and ensuring they align with real-world observations. This analysis allows researchers to refine models, validate hypotheses, and make informed decisions based on quantitative data.
