Until now, we have been dealing with numeric computation where variables store numeric values. In Chapter 7, you learned that numerical computation involves working with approximate solutions. On the other hand, an analytical solution is not an approximation since one uses symbols rather than numbers. MATLAB provides the means to perform symbolic computations, too.
8.2 Defining a Symbolic Variable
The keyword syms is used to define single or multiple symbolic variable(s). The key feature of a symbolic variable is that it just stores a symbol to perform ...
