9.3. Symbolic Mathematics

In MATLAB, generally all the calculations are done numerically, i.e., for every problem, the answer obtained is a numeric value. Another way of calculation is symbolic computation, i.e., the computation is done symbolically. For performing symbolic computation, ‘Symbolic Math Toolbox’ is available. This toolbox specifies a data type in MATLAB called a symbolic object. This data type stores a string representation of the symbol. The symbols as objects are used to express symbolic variables, expressions and matrices. The difference in numeric and symbolic computations is illustrated as follows:
