In some cases, such as parameter degeneracy, the Fisher matrix is singular and cannot be inverted; this has an impact on certain methods:
FisherMatrix.inverse
FisherMatrix.marginalize_over
FisherMatrix.correlation_matrix
FisherMatrix.constraints
FisherBaseFigure.plot
plot_curve_1d
plot_curve_2d
The code should catch these errors (numpy.LinAlgError), and handle this somehow. Some suggestions (a combination of these would also work):
show a UserWarning
when calling any plotting methods, plot parallel lines; this is a bit challenging as autoscale_view would make anything else drawn on the axis look tiny, but this can be fixed somehow (see this and this SO questions).
something else?
