Solve a basic (matrix) equation

The function matches to parts of the matrix equation, using the named formats with row names and solves the matrix equation.

Usage

equation_solve(LHS = NULL, Im = NULL)

Arguments

LHS

A left-hand side vector with a key column containing the industry or product names for matching, for example the employment coefficients.

Im

A Leontief-inverse with a key column containing the industry or product names for matching.

Value

A data.frame with auxiliary metadata to conform the symmetric input-output tables.

Details

This function is used in wrapper functions, such as multiplier_create. to solve particular problems, but it can be used directly, too. The function only performs the lhs pairing industries and checking for exceptions.

Examples

Im = data.frame (
a = c("row1", "row2"), 
b = c(1,1), 
c = c(2,0))
LHS = data.frame (
a = "lhs", 
b = 1, 
c = 0.5)
equation_solve (Im = Im, LHS = LHS)
#>        b c
#> [1,] 1.5 2
