  The Nearest Neighbour Spacing (NNS) distribution can be computed for
generalized symmetric 2x2 matrices having different variances in the diagonal
and in the off-diagonal elements. Tuning the relative value of the variances we
show that the distributions of the level spacings exhibit a crossover from
clustering to repulsion as in GOE. The analysis is extended to 3x3 matrices
where distributions of NNS as well as Ratio of Nearest Neighbour Spacing (RNNS)
show similar crossovers. We show that it is possible to calculate NNS
distributions for Hermitian matrices (N=2, 3) where also crossovers take place
between clustering and repulsion as in GUE. For large symmetric and Hermitian
matrices we use interpolation between clustered and repulsive regimes and
identify phase diagrams with respect to the variances.
