Symbolic Variables and expressions:

The MATLAB has a type known as sym for the symbolic variables and expressions; these work with strings. The illustration, to generate a symbolic variable a and execute the addition, at first a symbolic variable would be generated by passing the string 'a' to the sym function:

>> a = sym('a');

>> a+a

ans =

2*a

 

Also the Symbolic variables can store expressions. For illustration, the variables b and c store symbolic expressions as:

>> b = sym('x^2');

>> c = sym('x^4');
