edu.ucla.sspace.matrix.GrowingSparseMatrix

A growing sparse {@code Matrix} based on the Yale Sparse Matrix Format. Eachrow is allocated a pair of arrays which keeps the non-zero column values in column order. Lookups are O(log n) where n is the number of non-zero values for the largest row. Calls to set and setColumn can expand the matrix by both rows and columns.

Calls to {@link #getRowVector(int) getRowVector} and {@link #getColumnVector(int) getColumnVector} return a snapshot of the matrix dataat the time of the call. Subsequent updates to the matrix will not be reflected in these vectors. The returned vectors are immutable and any calls to mutating operations will throw an {@code UnsupportedOperationException}.

This class is not thread-safe. @author Keith Stevens
