Inner matrix dimensions must agree帮帮下?
我的这个程序哪错了。急帮看看。怎么就是不行，。>> theta1_U=2.7925; theta2_L=-1.7628; theta2_U=1.7628;
>> theta3_L=-1.8326; theta3_U=1.8326; theta4_L=-2.7925; theta4_U=2.7925;
>> theta5_L=-2.0944; theta5_U=2.0944; theta6_L=-18.8495; theta6_U=18.8495;
>> L3=315; L2=287; Lt=226;
>> B=zeros(5000,1); A=zeros(5000,1); C=zeros(5000,1); i=1;
>> while i<=5000; rand=0:0.1:1;

急啊。哪位有高手帮帮吧:'( :'( :'(
我这个到theta6都对的。一加上P_y=。。的就不对了。end 后就会说错了为什么啊，是不是P_y=后面的试子有错啊。帮帮吧:@( :@(
还是while 有的不对
