# Pad with zeros (zero padding is common in signal processing) padded_signal = np.zeros(10) padded_signal[:len(signal)] = signal print(padded_signal) # Output: [1. 2. 3. 4. 5. 0. 0. 0. 0. 0.] Padding signals with zeros using np.zeros() is a common technique to align or ...
使用占位符创建数组,例如函数zeros创建一个全是0的数组,函数ones创建一个全是的数组,函数empty创建一个内容随机并且依赖于内存状态的数组。 利用arrange创建数组:arrange(10,30,5),从10开始,每次加5,直到30(不包括) 2、打印数组,类似于嵌套列表。 3、数组的算数运算按元素进行,NumPy中的乘法运算符*指示按元素...

类似的函数还有np.zeros_like() np.equal(): 输入两个形状相同的数组(或两个数),逐个比较数组中元素是否相等,返回布尔值数组(或一个布尔值)。 >>>np.equal([1,2,3], [1,2,4]) array([True, True, False]) 1. 2. 若输入为一个数和一个数组,则将数组中每个元素与这个数进行比较,返回布尔值数组...
