Resolvable Matrices and Blocks#
Not every computed result in MARIO has a dedicated Python method. Many are exposed as named blocks that you access through the generic compute API:
db.resolve("Xa")
db.resolve_many(["u", "s", "Xc"])
db.calc_all(["fc", "pc"])
db.Xa
db.wcc
Use mario.CoreModel.available_matrices to list the block names accepted by the current table, and mario.CoreModel.get_block_spec to inspect their semantic axes.
For SUT databases, the built-in split and quadrant blocks include U, u,
S, s, Xa, Xc, Va, Vc, Ea, Ec, Ya, Yc,
wcc, wca, wac, waa, fa, fc, ma, mc, pa and
pc. The canonical commodity production vector name is Xc; Cx is
not a built-in MARIO matrix name.
The reference table below reuses the authoritative nomenclature matrix catalog and therefore covers both IOT and SUT built-ins, along with their table format, mode and default axes.
