When you use the syntax A = sym("a",[n1 ... nM]), the sym function assigns only the symbolic array A to the MATLAB workspace. To also assign the automatically generated elements of A , use the syms function instead.

Define the symbolic function f(x,y) = x + y. First, create the function by using syms. Then define the function.
Symbolic functions represent math functions. Use symbolic functions for differentiation, integration, solving ODEs, and other math operations. Create symbolic functions by using syms .
Create Symbolic Variable in Function. To declare a symbolic variable within a function, use sym. For example, you can explicitly define a MATLAB variable x in the parent function workspace and refer x to a symbolic variable with the same name.
Create symbolic variables, expressions, functions, and set preferences. Symbolic Math Toolbox™ introduces a special data type — symbolic objects. This data type includes symbolic numbers, symbolic variables, symbolic expressions, and symbolic functions.
We can define symbolic functions using the sym command and syms command. Here is an example of creating a symbolic function for (a*X^2) + (b*x) + c: >> syms a b c x % define symbolic math variables. >> f = sym('a*x^2 + b*x + c'); . From now on we can use the f symbol to represent the given function.
This MATLAB function declares a function named myfun that accepts inputs x1,...,xM and returns outputs y1,...,yN.
