发帖数: 5 | 2 有一个线性规划问题，想用Simplex解决,未知数X为47维
enj是47维向量，M1和M2均为1000*48维矩阵，
运行下列语句的时候
simplex(a=enj,A1=M1[,2:48],b1=t(M1[,1]),A2=M2[,2:48],b2=t(M2[,1]),maxi=TRUE)
提示错误如下
Error in as.vector(X) %*% t(as.vector(Y)) : non-conformable arguments
取消了b1和b2的转置提示同样的错误
请问有人知道是哪里写错了么，谢谢 |

I was once obsessed with classic music, and even after many years of totally
