    This function computes the self-similarity matrix for a sequence of feature vectors.
    ARGUMENTS:
     - featureVectors:     a numpy matrix (nDims x nVectors) whose i-th column corresponds to the i-th feature vector

    RETURNS:
     - S:             the self-similarity matrix (nVectors x nVectors)
