"NettetThe problem has a linear equality constraint x 1 = 0. 3 x 2, which you can write as x 1 - 0. 3 x 2 = 0. The problem also has three linear inequality constraints: 0. 1 x 5 ≤ x 4 x 4 ≤ 0. 5 x 5 0. 9 x 5 ≤ x 3. Represent the bounds and linear constraints as matrices and vectors. The code that creates these arrays is in the fullexample function. " - Linear equality constraints
