MATSOLVE: Solve system of linear equations put in matrix-vector form

syntax: MATSOLVE
(
(a11, a12, a13, ... | b1)
(a21, a22, a23, ... | b2)
(a31, a32, a33, ... | b3)
...
(aN1, aN2, aN3, ... | bN)
)

returns the solution as: x1 = value1, x2 = value2, ... xN = valueN for each variable x1...xN in the system of equations. a11...aN3 denotes the coefficients for each variable. b1...bN denotes to right-side value of each equation. The number of rows in the matrix must be equal to the number of columns (not including the right-side value column), otherwise the function will halt with an error message.
