Symbolic Functions in MATLAB

MATLAB provides an array of functions that enable you to analyze symbolic expressions, solve equations and manipulate variables. These include functions for integrating, differentiating, minimization and solving differential equations as well as functions from Symbolic Math Toolbox for performing transforms and dimension computations.

Use syms to dynamically create symbolic variables and index into them to solve expressions, helping you evaluate them all at the same time. Furthermore, they allow you to assign symbolic functions directly onto vectors or cell Arrays.

However, you cannot index into a symbolic function with a vector argument as its symbolic engine interprets this type of vector as numeric variables and cannot index into them directly.

Example: When creating and assigning a symbolic expression like f(x2,y2) to symbolic matrix variables x1_1 and y1_1, Syms only evaluates its right hand side; that is, it evaluates f(x2,y2) in order to create a new expression based on elements in the matrix; but does not evaluate contents of either symbolic variable as they do not comprise part of this expression – thus leading to unexpected results if using its results as input into non-symbolic functions – which would otherwise require using results of symbolic functions as input. This behavior is intended as it helps prevents you from using results of symbolic functions as input into non-symbolic functions resulting in unexpected results which might otherwise result from using symbolic functions results as input instead.
