eye dtype

The definition of the eye function has an optional parameter dtype with float as default value.

def eye(m, n=None, k=0, dtype='float'):

However, it returns a lazy linear operator with dtype='float'.

return LazyLinearOp((m, n), matmat=lambda x: matmat(x, m, n, k),
                              rmatmat=lambda x: matmat(x, n, m, -k),
                              dtype='float')
