Description of The Method
Suppose we want to solve the following system of linear equations
- Ax = b
for the vector x where the known n-by-n matrix A is symmetric (i.e. AT = A), positive definite (i.e. xTAx > 0 for all non-zero vectors x in Rn), and real, and b is known as well.
We denote the unique solution of this system by .

“God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.”
