Abstract
For a nonlinear differential matrix equation, we study a multipoint boundary value
problem by a constructive method of regularization over the linear part of the equation using the
corresponding fundamental matrices. Based on the initial data of the problem, sufficient
conditions for its unique solvability are obtained. Iterative algorithms containing relatively simple
computational procedures are proposed for constructing a solution. Effective estimates are given
that characterize the rate of convergence of the iteration sequence to the solution, as well as
estimates of the solution localization domain.
