From source file:edu.byu.nlp.util.asserts.MoreAsserts.java

public static void assertSparseMatricesEqual(final SparseRealMatrix actual, final SparseRealMatrix expected) {
    Preconditions.checkNotNull(actual);//from www .j ava 2  s.c om
    Preconditions.checkNotNull(expected);
    Preconditions.checkArgument(actual.getRowDimension() == expected.getRowDimension());

    // check densely--this doesn't need to be fast
    for (int r = 0; r < actual.getRowDimension(); r++) {
        for (int c = 0; c < actual.getColumnDimension(); c++) {
            double act = actual.getEntry(r, c);
            double exp = expected.getEntry(r, c);
            if (act != exp) {
                System.err.println("actual[" + r + "][" + c + "]=" + act + " does not match expected[" + r
                        + "][" + c + "]=" + exp);
            }
