Display a list of all symbolic scalar variables, functions, matrix variables, matrix functions, and arrays that currently exist in the MATLAB workspace by using syms.

If you want to create a MATLAB array of numbered symbolic variables, you can use the sym or the syms syntax. Use sym to create an array of many numbered symbolic variables.

Use the syms function to create a symbolic variable x and automatically assign it to a MATLAB variable x. When you assign a number to the MATLAB variable x, the number is represented …

Create and Define Symbolic Functions Define the symbolic function f(x,y) = x + y. First, create the function by using syms. Then define the function.

Create the polynomial: syms x f = x^3 - 15*x^2 - 24*x + 350; Create the magic square matrix: A = magic(3) A = 8 1 6 3 5 7 4 9 2

Alternatively, to use the parameters in the MATLAB workspace use syms to initialize the parameter. For example, if the parameter is k, use syms k. The variable names parameters …

Create Symbolic Matrices Use Existing Symbolic Variables A circulant matrix has the property that each row is obtained from the previous one by cyclically permuting the entries one step …

To create symbolic expressions, first create symbolic variables, and then use operations on them. For example, use syms x; x + 1 instead of sym ('x + 1'), exp (sym (pi)) instead of sym ('exp …

For further computations, clear the assumption on x by recreating it using syms.

Symbolic Math Toolbox provides functions for solving, plotting, and manipulating symbolic math equations.
