О НЕКОТОРЫХ АНАЛОГАХ ФОРМУЛ СПЛАЙН-ИНТЕРПОЛИРОВАНИЯ ДЛЯ ФУНКЦИЙ МАТРИЧНОЙ ПЕРЕМЕННОЙ

Analogs of interpolation splines for functions of matrix variable, defined on sets of matrices with the ordinary, Jordan, Hadamard and Frobenius multiplication, has been constructed. Some of the obtained formulas contain Gateaux differentials of the interpolated function.
