heard that mathematica is good, some say its better than matlab .
You can't really compare the two directly. Mathematica has a strong focus on symbolic operations (solve differential equations analytically, do integrals and derivatives, expansions, etc) , it can simplify complicated expressions by using all kinds of identities, and provides an entire functional programming language. While it also has an extensive numerical functionality, it gets inefficient and slow very fast when handling large data sets.and very large formulas.
One application we use Mathematica for is to calculate the analytical expressions for particle scattering from feynman diagrams. Mathematica has a nice capability to generate and manipulate the resulting expressions. The resulting formulas can have several megabytes in text, though, and are usually passed to more efficient (but "dumber") computer algebra such as FORM.
