Forward and backward substitution matlab
WebThe Forward Substitution block solves the linear system LX = B by simple forward substitution of variables, where: L is the lower triangular M -by- M matrix input to the L port. B is the M -by- N matrix input to the B port. X is the M -by- N output matrix and is the solution of the system of equations. The block does not check the rank of the ...
