Numerical calculation method is a basic course for mathematics majors (such as information and calculation, mathematics and applied mathematics), which mainly includes three parts: numerical approximation, numerical algebra and numerical solution of differential equations. With the advancement of the credit system reform, this course can also be used as an elective course for some engineering students in the school. In the past, most of the contents of the course "Calculation Method" of some engineering students in our school were included in the course "Numerical Calculation Method".

With the development of computer technology and the progress of science and technology, the application scope of scientific computing has been extended to many disciplines and some marginal disciplines have been formed. Such as computational physics, computational mechanics, computational chemistry, etc. At present, experiment, theory and calculation have become the three major methods for people to carry out scientific activities. It is very necessary for people engaged in engineering and science and technology to learn and master numerical calculation methods.

Numerical calculation method is a branch of mathematics, but different from pure mathematics, it only studies the theory of mathematics itself, but closely combines mathematical theory with calculation method, which has the characteristics of high abstraction, wide application and high practical experimental technology content. It is a practical mathematics course closely combined with computer use, with emphasis on numerical methods and theories of mathematical problems.
