AND x
... Recall that the absolute value of a number x, written |x|, is the distance from x to zero on the number line. Because absolute value represents distance without regard to direction, the absolute value of any real number is nonnegative. ...

MATLAB Lecture #2
... Advantage of using left division In general, x = A\b is more stable and faster. Why? Some reasons include: • inv(A) may not exist • x = A\b uses Gaussian elimination and: • Scales matrix entries to minimize errors • Uses faster algorithms for special matrices, such as sparse, symmetrical or banded m ...

... “ ” in (1-7) represents “otherwise”, it can be read as “extraction”. Equation (1-7) is in fact a set of congruence equations. As the module of each equation has two possibilities, the combination of nine equations produces 2 512 congruence equations. The modular domain ...
