Specifies the bandwidth reference value used in automatic IS-IS interface cost calculation. The value is an integer that ranges from 1 to 2147483648, in Mbit/s. Views IS-IS view Default Level 2: Configuration level Usage Guidelines Usage Scenario To make the set link cost of IS-IS routes...
function r = mbInteger(A,idx) arguments A (1,:) {mustBeNumeric} idx (1,1) {mustBeInteger} end r = A(idx).^2; end Calling this function with a noninteger value results in an error being thrown by mustBeInteger. The result of dividing two random integers can result in an integer...
Operating dimension, specified as a positive integer scalar. If no value is specified, then the default is the first array dimension whose size does not equal 1. Consider an m-by-n input matrix, A: islocalmax(A,1) computes local maxima according to the data in each column of A and re...
取Java 类中的字段:a = new Integer(11); a.value 调用Java 类中的方法:Math.abs(12) 脚本可以: 使用QLExpress 的自定义操作符/宏/函数,以此实现与应用的受控交互 使用. 操作符获取 Map 的key 对应的 value,比如 a 在应用传入的表达式中是一个 Map,那么可以通过 a.b 获取 所有不涉及应用 Java 类的操...
In this regime, the lines with finite slopes all represent the standard integer quantum Hall states. The second quantity we calculate is the spin susceptibility defined as $${\chi }_{s}=\mathop{\sum}\limits_{{{\bf{r}}}S({{{\bf{r}}})-N{m}_{z}^{2}=\frac{1}{N}\mathop{\sum...
Delay can be Integer, Float or Range (2..5). In case of a Range, delay number will be chosen randomly for each request: rand (2..5) # => 3 engine: set custom engine than a default one: in_parallel(:method, urls, threads: 3, engine: :poltergeist_phantomjs) config: pass custom...
Each successively activated cabal and commonwealth locus is indexed with a consecutive integer within the respective sets Icabal = {1, 2, …, ncabal} and Icommonwealth = {1, 2, …, ncommonwealth}, where ncabal and ncommonwealth give respectively the total number of activated ...
