matlab做线性规划中一个报错无法解决望各位解惑！

Question

用matlab做一个关于线性规划的问题，但是出现以下形况望各位解惑！
matlab版本为2022a
代码：
clc,clear
x = optimvar('x',4,3,'LowerBound',0);
wh = [18,15,23,12];
wj = [10,16,8];
vj = [6800,8700,5300];
rou = [18/480,15/650,23/580,12/390];
lirun = [3100,3800,3500,2850];
a = sum(x,2);
b = sum(x);
z = lirun*a;
prob = optimproblem('Objective',z,'ObjectiveSense','max');
prob.Constraints.c1 = a <= wh';
prob.Constraints.c2 = b' <= wj';
prob.Constraints.c3 = sum(x(1:4,1)./rou') <= 6800;
prob.Constraints.c4 = sum(x(1:4,2)./rou') <= 8700;
prob.Constraints.c5 = sum(x(1:4,3)./rou') <= 5300;
prob.Constraints.c6 = vj(1)/b(1) == vj(2)/b(2);
prob.Constraints.c7 = vj(1)/b(1) == vj(3)/b(3);
[sol,fval] = solve(prob);
sol.x
fval
报错：
错误使用 optim.problemdef.OptimizationProblem/solve
SOLVE requires a non-empty initial point structure to solve a nonlinear problem.
