Description

Per javadocs, Matrices.symmetricUniformView(...) is meant to return values in on the range of [-1,1):

/**
   * Matrix view based on uniform [-1,1) distribution.
   *
   * @param seed generator seed
   */
  public static final Matrix symmetricUniformView(final int rows,
                                                  final int columns,
                                                  int seed) {
    return functionalMatrixView(rows, columns, uniformSymmetricGenerator(seed), true);
  }

Ranges being returned now are on (-.5,.5).
