Simplify Symbolic Expressions. Symbolic Math Toolbox provides a set of simplification functions allowing you to manipulate the output of a symbolic expression.The idea that I am using in the convergence of the series is mathematical, i.e., converges if norm of each term after some finite 'n' must be less than some predefined small value (eps in my case). For inner sum, while loop stops after value of 'Lth term' is less than 'eps' and the outer while loop stops when the norm of inner sum gets less than 'eps'.1. The Symbolic Toolbox operates from the standpoint that Symbolic Variables are scalars and any operation or expression in which they are present uses element-wise semantics.
