Description: For the group consisting of n unknowns, n equations consisting of a multivariate equations:
a11X1+ a12X2+. . .+ a1nXn = b1
a21X1+ a22X2+. . .+ a2nXn = b2
. . . . . .
an1X1+ an2X2+. . .+ annXn = bn
Written in matrix form as Ax = b, where A is the coefficient n* n matrix, x is a column vector of n variables constituting, b is a constant term n column vectors constituting. When it s reversible coefficient matrix, or the corresponding determinant | A | is not equal to 0, by the Ax = b can be obtained: x = b* A-1, A-1 is the inverse matrix A.
