16 мар. 2020 г. · You can do Cauchy principal-value integrals easily using any integration package (eg QuadGK.jl) using a simple transformation that eliminates the singularity.

With these programs, the function defined by arithmetic operations,fundamental functions, conditional statements, etc. can be easily expanded to Taylor series.

This chapter describes routines for performing numerical integration (quadrature) of a function in one dimension.

We investigate the possibility of fast, accurate and reliable computation of the Cauchy principal value integrals ⨍ a b f ( x ) ( x − τ ) − 1 d x ( a < τ ...
