Special functions

functions which have established names and notations due to their importance in mathematics
Special functions are some mathematical functions used in mathematical analysis or physics.[1][2][3] Most of them appear in higher education. Some experts are studying numerical methods for them.[4]
In mathematics, most functions are defined as a solution of a differential equation.[1] For example, the exponential function is the solution of the ordinary differential equation . Due to this relation, some mathematicians are studying the connection between ODEs and special functions.[1][5]
- Gamma function, it is studied since Euler[1][6][7]
- Orthogonal polynomials, these are polynomials with special properties.[8][9][10]
- Matrix functions, these are studied in linear algebra and matrix analysis.[11]
