Dear all,
I have been asked to forward the below to the sage-devel list. Ticket
#6290 introduced a way to custom-define the latex style of functions,
but it would be great if something similar was made possible for any
variable. Is there a way for this already? I used to do it in the
following way, but now I get an error message:
sage: var('hi kunsati delyui')
sage: hi._latex_ = lambda: 'h_i' # Matric suction
head in layer i (=pcapvec)
sage: kunsati._latex_ = lambda: 'K_{unsat,i}' # Unsaturated
hydraulic conductivity in layer i
sage: delyui._latex_ = lambda: '\delta_{yu,i}' # Soil layer
thickness in layer i
Traceback (most recent call last):
...
AttributeError: 'sage.symbolic.expression.Expression' object attribute
'_latex_' is read-only
I already posted this to sage-support, so sorry for any cross-posting.
Cheers,
Stan

Hmmm, thats a great suggestion. Could you please post this to sage-devel?
