Given a matrix of priority function values, return a matrix in which each row gives the column indices of the corresponding row in the priority matrix, when that row has been sorted from highest to lowest priority value.
prioritize_cols(priority_matrix)A numeric or integer matrix. Rows represent time (ordered from most recent to most distant), columns represent e.g. locations or data streams (numbered from 1 and up). The element in row \(i\) and column \(j\) holds the priority of the \(j\)th location/data stream for times \(1,\ldots,i\).
A matrix of the same size as the input. On each row, column indices are given in order of priority.
