模板函数是容器类矢量上专用化的算法,用以执行成员函数left. vector::swap (right)。 这些是由编译器进行的函数模板部分排序的实例。 模板函数以此种方式重载时,模板与函数调用的匹配并不唯一,随后编译器会选择此模板函数的最专用化版本。 模板函数的通用版本,template <class T> void swap(T&, T&),在算法类中...

v2class library in its version 3.0 has undergone considerable changes. We now havev2objects as well asv2static functions. Latter work with arbitrary objects as long as these exposexandymembers orxandygetters and setters. v2objects Properties ...
Mdl = fitcecoc(Tbl,ResponseVarName) returns a full, trained, multiclass, error-correcting output codes (ECOC) model using the predictors in table Tbl and the class labels in Tbl.ResponseVarName. fitcecoc uses K(K –1)/2 binary support vector machine (SVM) models using the one-versus-one...
