vector类为内置数组提供了一种替代表示,与string类一样 vector 类是随标准 C++引入的标准库的一部分 ,为了使用vector 我们必须包含相关的头文件 :
An arrangement is provided for computing the magnitude value of the vector sum of two quadrature-related component signals I and Q with a minimal of hardware. To this end, the magnitude values of the orthogonal I and Q signals are applied to a ROM as address codes to produce the LogB I ...

In this exercise you will train a spam classifier using support vector machines. We will use the spam dataset which comes with the {kernlab} package. First, we will split the spam data randomly into two halves: one half we will use as the training data, the other half we will use ...
