描述

get_sample_num_class_knnget_sample_num_class_knnGetSampleNumClassKnnGetSampleNumClassKnnGetSampleNumClassKnnget_sample_num_class_knn returns in NumSamplesNumSamplesNumSamplesNumSamplesnumSamplesnum_samples the number of training samples that are stored in the k-nearest neighbors (k-NN) classifier given by KNNHandleKNNHandleKNNHandleKNNHandleKNNHandleknnhandle. get_sample_num_class_knnget_sample_num_class_knnGetSampleNumClassKnnGetSampleNumClassKnnGetSampleNumClassKnnget_sample_num_class_knn should be called before the individual training samples are accessed with get_sample_class_knnget_sample_class_knnGetSampleClassKnnGetSampleClassKnnGetSampleClassKnnget_sample_class_knn。

执行信息

多线程类型：可重入（与非独占算子并行运行）。
多线程作用域：全局（可从任何线程调用）。
未采用并行化处理。

参数

KNNHandleKNNHandleKNNHandleKNNHandleKNNHandleknnhandle (输入控制) class_knn → (handle)

k-NN 分类器的句柄。

NumSamplesNumSamplesNumSamplesNumSamplesnumSamplesnum_samples (输出控制) integer → (integer)

Number of stored training samples.

结果

If KNNHandleKNNHandleKNNHandleKNNHandleKNNHandleknnhandle is valid, the operator get_sample_num_class_knnget_sample_num_class_knnGetSampleNumClassKnnGetSampleNumClassKnnGetSampleNumClassKnnget_sample_num_class_knn 返回值 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
