While all outputs must lie in Codom(f), not every number in codom(f) need to be an output value. Codomain的定义一定要跟后边的range区分开来. 我们用下面一张图来解释: 函数f:X->Y 的定义域是图中红色的部分,这个是函数的定义域, 我们暂时用maximal domain, 通过函数f的映射,f(x)所能取到的...
Mothers and Daughters Analogy A way to try to understand this concept is to think of how mothers and their daughters could be represented as a function. Each element in the domain, each daughter, can only have 1 mother (element in the range). Some people find it helpful to think of the...

The fractional and regular second-order GVD coefficients in Eq. (2) are fixed as D = 21 × 10−3 psα/m and β2 = − 21 × 10−3 ps2/m, respectively. b Experimental results for cases Q1–Q4 and B2. c The Wigner functions in the time–frequency ...
return math.acos(x) print(safe_acos(2)) This will raise aValueError, with a clearer message Conclusion The “ValueError: math domain error” in Python is usually caused by trying to compute math functions with input values that make the function mathematically undefined. ...
And another function g(x) = x2 can have the domain of integers {...,-3,-2,-1,0,1,2,3,...}, in which case the range is the set {0,1,4,9,...}Even though both functions take the input and square it, they have a different set of inputs, and so give a different set ...
where the \bf \mathcal{H}\triangle\mathcal{H}\text{-}divergence is defined as \bf d_{\mathcal{H}\triangle\mathcal{H}}(P_X^s,P_X^t):=sup_{h,h'\in mathcal{H}}|\epsilon^s(h,h')-\epsilon^t(h,h')| replaces the total variation d_1 to measure the distribution difference...

Topologically associating domains (TADs) are critical structural units in three-dimensional genome organization of mammalian genome. Dynamic reorganizations of TADs between health and disease states are associated with essential genome functions. However, computational methods for identifying reorganized TADs ar...
