The role of syms in matlab is to define symbolic variables. Its usage syntax is as follows: 1. Define a symbolic variable x through "syms x"; 2. Create symbolic variables x and y through "syms x y"; 3. , create arrays through "syms a f(x);A = sym('A',[2 3]);", etc.

The role of syms in matlab is to define symbolic variables.
1. Define a symbolic variable x
syms x
2. Create symbolic variables x and y
syms x y
3. List all symbolic variables, functions and arrays
Create some symbolic variables, functions and arrays such as:
syms a f(x)；A = sym('A',[2 3]);
Use syms to display a list of all symbol objects currently existing in the MATLAB workspace. Then the symbol variable is:
A A f x；
Instead of displaying a list, a cell array of all symbol objects is returned by providing output to syms. Such as:
S = syms；S = 4×1 cell array {'A'} {'a'} {'f'} {'x'}；
