The matrix operations of addition, scalar multiplication, negation and subtraction satisfy the usual laws of arithmetic. (In what follows, s and t are arbitrary scalars and A, B, C are matrices of the same size.) 1. (A + B) + C = A + (B + C); 2. A + B = B + A; 3. ...
where each array has the sizen1-by-...-by-nMand contains automatically generated symbolic scalar variables as its elements. For example,syms a [1 3]creates the symbolic arraya = [a1 a2 a3]and the symbolic scalar variablesa1,a2, anda3in the MATLAB®workspace. For multidimensional ...
return log(y) - (z - x) / y ; /* cancels errors with IEEE arithmetic */ } 1. 2. 3. 4. 5. 6. 7. 经过实际验算,这个算法可以保证15位的有效数字。很神奇的算法,先计算 log (1+x),然后在做修正,而且只做了个1阶修正就能达到如此好效果,很让我惊讶。为什么会这样我现在的水平还解释不了...
The class of matrix arithmetic attained is remarkably broad, encompassing primitives as diverse as Hamiltonian simulation, matrix inversion, ground-state energy estimation, Gibbs-state sampling, among others4. Moreover, the framework often offers the state-of-the-art in asymptotic query complexities (...
Some of the matrices in this chapter will be used to illustrate some of the properties of matrix arithmetic, which is the topic of the next section. For example, we will show that rotating first and then shearing is not the same as shearing first and then rotating. Hence, matrix multiplica...

First, create a 3-by-3 matrix A using variable-precision arithmetic with five digit accuracy. In this example, using variable-precision arithmetic instead of exact symbolic numbers lets you speed up computations and decrease memory usage. Using only five digits helps the result to fit on screen...
