Changed property use_tridiagonal for tridiagonal_form in GaussianEnsemble and WishartEnsemble classes.
Added new method resample with the option of specifying the bool argument tridiagonal_form (by default None), which allows changing the pre-defined form of the matrix
Update ylabel of the spectral_law plots to be always "density", and not "probability density".
Update ylabel of the ensemble plots to be "density" if density=True, and "frequency" if density=False.
Added the method _plot_eigval_hist to ManovaEnsemble class so the default interval con be correctly specified.
Added test_standard_vs_tridiag_hist method in utils to compare the histograms of random matrices in their tridiagonal form vs their standard form.
Renamed method set_eigval_norm_const: now it is a private method.
