我正在尝试使用R-软件解决下面表格中的7x2矩阵问题:
A=array(c(5.54,0.96,1.59,2.07,0.73,10.64,8.28,1.41,3.77,3.11,3.74,2.93,8.29,3.33), c(7,2))
A
# [,1] [,2]
#[1,] 5.54 1.41
#[2,] 0.96 3.77
#[3,] 1.59 3.11
#[4,] 2.07 3.74
#[5,] 0.73 2.93
#[6,] 10.64 8.29
#[7,] 8.28 3.33
b=c(80814.25,34334.75,47921.75,59514.25,26981.25,63010.25,46646.25)
b
#[1] 80814.25 34334.75 47921.75 59514.25 26981.25 63010.25 46646.25
solve (A,b)
Error in solve.default(A, b) : 'a' (7 x 2) must be square
A %*% solve (A,b)
Error in solve.default(A, b) : 'a' (7 x 2) must be square
您认为我能怎样做才能解决问题.如上所述,我需要在7x2矩阵中解决两个变量x1和x2.
