The authors give an introduction to Maslov’s method of noncommutative analysis. It is explained how to define a function of several noncommuting operators using Feynman’s convention. An application to an algebra of operators $$\{f(\overset {1} {A}_ 1,\dots,\overset {n} {A}_ n)\}$$ in the case when the commutators $$[A_ j,A_ k]$$ are linear functions of $$\{A_ i\}$$ is considered as well.
