Python numpy iscomplex用法及代碼示例本文簡要介紹 python 語言中 numpy.iscomplex 的用法。 用法: numpy.iscomplex(x) 返回一個 bool 數組,如果輸入元素是複數,則返回 True。 測試的是輸入是否具有非零虛部,而不是輸入類型是否複雜。 參數: x: array_like 輸入數組。 返回: out: 布爾數組 輸出數組。 例子...
Python numpy.iscomplex() Python numpy.iscomplex()函数按元素测试它是否是复数(不是无穷大或不是数字),并将结果作为布尔数组返回。 语法 : numpy.iscomplex(array) 参数 : array : [array_like] 输入数组,我们要测试其元素。 返回 : 包含结果的布尔数组 示例 1
