We propose two algorithms for particular cases of block-recursive LU -decomposition of matrices over idempotent semifields. We consider the cases in which the band width of the block is equal to 1 or 2. For each of them we will get the decomposition algorithm and give an example.
Предлагаются алгоритмы для двух частных случаев блочно-рекурсивного LU -разложения матриц над идемпотентными полуполями. Мы рассматриваем случаи, в которых блочная полоса имеет ширину 1 или 2. Для каждого из них мы получаем алгоритм разложения и приводим пример.
