Abstract
This Technical Document describes the foundations for an aggregation matrix function implemented in MATLAB, including the format and structure of the required aggregation vector used as an argument to the function. The function is passed with the Ndimensional aggregation vector as an argument. The aggregation vector contains N values ranging from 1 to M, each of which is the aggregate index corresponding to the N preaggregation indices. The function returns an aggregation matrix with M rows and N columns. Pre-multiplying an existing matrix with N rows by the aggregation matrix reduces the row dimensionality from N to M by adding the sectors to be aggregated. Post-multiplication by the transpose of the aggregation matrix reduces the column dimensionality from N to M accordingly.
