At present, the field of computer science that can be widely used to generate high-number lines belongs to the field of engineering. Such as fluid mechanics, elastic mechanics, material mechanics, etc. In fluid mechanics, it is typical to use finite element method to deal with the motion of ideal fluid in viscous fluid. Empty drawing technology of stainless steel flexible thin tube in engineering. When there are a large number of data matrices, matrix algorithm is used to simplify the operation.

In addition, complex function is widely used in electronic design in the physical field. For example, the quantum field theory of solving the wave function of linear equations in quantum mechanics in circuit theory, in which the rotation of Wick involves the integral calculated in I-body theory, many of them use residue theorem, especially the wave color distribution and Fermi distribution (usually postponed to Songyuan frequency), and there are many examples in which complex numbers can simplify the calculation.

Natural language processing also has a large number of applications for generating high-order lines. For example, how different natural languages use machine translation and speech recognition. Data communication, etc. Moreover, it is difficult to handle these manually, and most of them need computer assistance. Therefore, it is necessary to learn computer. But I learned little.
