Abstract
In this paper, an algorithm is constructed for finding the block trian gular form of a nonnegative matrix. The algorithm is based on the zero elements of the left and right Perron vectors of the matrix and, subs equently, certain submatrices. The construction of the algorithm Is mo tivated by the empirica results of measuring sectoral interdependencie s in the production structure of an economy.
