Define coefficients of the linear equalities
Topics

Specification
Alias: None
Arguments: REALLIST
Default: no linear equality constraints
Description
In the equality case, the constraint matrix \(A\) provides coefficients for the variables on the left hand side of:
The linear_constraints topics page (linked above) outlines a few additional things to consider when using linear constraints.
Examples
An optimization involving three variables, x1
, x2
, and x3
, is to be
performed. These variables must satisfy a pair of linear equality constraints:
The pair of constraints can be written in matrix form as:
The coefficient matrix and right hand side are expressed to Dakota in the
