db.U

For the standalone function, see mario.calc_U().

Calculate commodity-by-activity use flows from use coefficients and activity production.

\[U=u\operatorname{diag}(X_a)\]

Inputs#

u: use coefficients, with commodity rows and activity columns.

Xa: activity production, indexed like the columns of u.

Result#

Commodity nodes on rows and activity nodes on columns. Each coefficient column is multiplied by its activity production.

Example#

import mario

db = mario.load_test("SUT", tech_assumption="IT")
result = db.resolve("U")
# Dotted access requests the same block:
result = db.U

Use resolve for scenario selection and recomputation options. Existing targets are reused. The other SUT equations are listed in Resolvable Matrices and Blocks.
