求教：如何用Matlab编写这个动态规划的程序

建立唤猜数学模型设xi=1表和稿型示Ai被选中，xi=0表示Ai没被选中。则数学模型是：max 1500x1+2000x2+1300x3+2300x4+2800x5s.t. x1+x2=1 x4+x5=1 x1+x4<=1 x2-x5=0 xi=0或1，i=1,2,3,4,5 2.编程求敬顷解matlab程序：f=[-1500-2000-1300-2300-2800]A=[10010]b=1Aeq=[11000000110100-1]beq=[110]x=bintprog(f,A,b,Aeq,beq)解出来是：x=01101也就是说运送A2,A3,A5
