1 order() function appears to not be working -- may be due to variable type 1 Passing undetermined number of arguments in R to the order() function 6 Order() function in r is not ordering correctly 1 Strange behavior of order function 0 What's wrong with order function in data ...
Order is defined as () The order function in R returns the ascending or descending position of each element in its input. Within our example vector, the lowest value (i.e. -5) is at position two, while the maximum value (i.e. 5) is at position 1. R function rank() definition: ...

我们可以知道,上图是E \times R的子集,且若(x,y) \in epi(f),则由于y \in R,故x \in dom(f)。 定义2.2 \quad(闭函数closed \quad functions)称广义实值函数f:E \rightarrow [-\infty,+\infty]为闭函数若它的上图是闭的。 将闭函数的定义应用到我们前面说到的最简单的广义实值函数的例子即指...
an elastic body 4 is provided so as to form a specific air layer 6 at the inner periphery of the groove 5, and a piston ring is provided on the outer periphery of the elastic body 4, so as to compose a system in order to maintain an airtight condition between the inner peripheral su...
在此情况下,(2.8)即等价于说明g(\lambda x_1+(1-\lambda)x_2) = -\infty。取任意M \in R,由于g(x_1) = -\infty,则存在y_1 \in V,使得: f(x_1,y_1) \le M 根据性质(2.7),存在y_2 \in V使得f(x_2,y_2) < \infty,利用f的凸性,可得:...
map()传入的第一个参数是f,即函数对象本身。由于结果r是一个Iterator,Iterator是惰性序列,因此通过list()函数让它把整个序列都计算出来并返回一个list。 当然,不需要map()函数,写一个循环,也可以计算出结果: deff(x):"""返回一个数的3次方 :param x: 数 ...

rhosa: Higher-Order Spectral Analysis in R This package aims to provide functions to estimate higher-order spectra or polyspectra of multivariate time series, such as bispectrum and bicoherence (Brillinger and Irizarry 1998). They are useful for e.g. detecting nonlinear interaction between stationar...
The anonymous function must accept two inputs (t,y), even if one of the inputs is not used in the function. Solve the ODE y′=2t. Specify a time interval of [0 5] and the initial condition y0 = 0. Get tspan = [0 5]; y0 = 0; [t,y] = ode78(@(t,y) 2*t, tspan,...
