Create Constraint Array

Create a 4-by-6 optimization variable matrix named x.

x = optimvar('x',4,6);

Create the constraints that each row of x sums to one.

constrsum = sum(x,2) == 1

constrsum = 

  4×1 OptimizationConstraint array with properties:

    IndexNames: {{}  {}}

  See constraint formulation with showconstr.

View the constraints.

showconstr(constrsum)

(1, 1)

  x(1, 1) + x(1, 2) + x(1, 3) + x(1, 4) + x(1, 5) + x(1, 6) == 1

(2, 1)

  x(2, 1) + x(2, 2) + x(2, 3) + x(2, 4) + x(2, 5) + x(2, 6) == 1

(3, 1)

  x(3, 1) + x(3, 2) + x(3, 3) + x(3, 4) + x(3, 5) + x(3, 6) == 1

(4, 1)

  x(4, 1) + x(4, 2) + x(4, 3) + x(4, 4) + x(4, 5) + x(4, 6) == 1

To include the constraints in an optimization problem, use dot notation.

prob = optimproblem;
prob.Constraints.constrsum = constrsum;
