E = weilToCartier(L,F)
L must a list of weights, exactly one for each ray of the fan. Then the list of weights for each ray describes a Weil divisor on the toric variety. If the Weil divisor defined by these weights defines in fact a Cartier divisor, then weilToCartier computes the toric vector bundle associated to the Cartier divisor.
If no further options are given then the resulting bundle will be in Klyachko's description:



If the option "Type" => "Kaneyama" is given then the resulting bundle will be in Kaneyama's description:



The object weilToCartier is a method function with options.
