For square matrices NO means that diagonal entries are ignored.

The name of an Ucinet dataset.To partition the rows of the data matrix into blocks, specify a blocking vector by giving the dataset name, a dimension and an integer value. For example, to use the second row of a dataset called ATTRIB, enter "ATTRIB ROW 2". The program will then read the second row of ATTRIB and use that information to sort the rows of the matrix. All rows with identical values on the criterion vector (i.e. the second row of attrib) will be placed in the same block of the matrix. Densities will then be computed separately for each block.
