Triangular system of equations
WebSome equation systems are said to be “ block recursive, ” meaning that the recursive or triangular property applies only to blocks made up of subsets of the equations in the model. If the system can be characterized as block recursive, then the endogenous variables listed in each block of equations may be jointly determined, but the blocks ...

WebLinear systems. We now attend to the central problem of this chapter: Given a square, n × n matrix A and an n -vector b, find an n -vector x such that Ax = b. Writing out these equations, we obtain. If A is nonsingular, then the mathematical expression of the solution is x = A − 1b, because. A − 1b = A − 1(Ax) = (A − 1A)x = Ix = x.
