Linear System of Equations Lx = b where the matrix L This procedure of solving a lower triangular system is called the general forward substitution. Example 2 3.2 Solution of Triangular Systems вЂ  Forward substitution: x1 = b1=l11 Column-Oriented Forward Substitution вЂ  Partition Lx = b as follows: h

The LowerTriangularSolver object solves LX = B for X when L is a square, lower-triangular matrix with the same number of rows as B. For example, y = step(obj,x) An awful lot of people seem to use the phrase "substitute X for Y That link isn't about for/with - it's about the problems caused when X and Y in OP's example

... x + y = 3, yields x = 2. (BackвЂђsubstitution of y = 1 into the original second the вЂњforwardвЂќ part of Gaussian elimination is (x, y, z) = (3, 2, 1 The marginal rate of substitution of X for Y is the amount of Y that will be given up for obtaining each additional unit of X. Definition:
