Найдены классы матричных многочленов, для которых интерполяционные формулы точны. Предложен способ построения на основе данного интерполяционного матричного многочлена фиксированной степени других интерполяционных многочленов той же степени, но с большим числом узлов.</p></abstract><trans-abstract xml:lang="en"><p>The interpolation formulas for operators of one, two and many functional matrix variables containing arbitrary matrices are constructed. The classes of matrix polynomials, for which interpolation formulas are exact, are defined. The method of construction based on a given fixed degree interpolation matrix polynomial of other interpolation polynomials of the same degree, but with more number of nodes is proposed.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Макаров В.
