tensorflow.math.special.fresnel\_cos() 函数TensorFlow是谷歌设计的开源python库,用于开发机器学习模型和深度学习神经网络。
fresnel\_cos() 函数fresnel\_cos()
用于计算元素明智的菲涅尔对x的余弦积分。它被定义为cos(t^2)从0到x的积分,定义域为所有正实数。
语法:
tensorflow.math.special.fresnel_cos( x, name)
参数 :
dtypes 是float32和float64。返回:
它返回一个与x具有相同dtype的张量。
示例 1:
# importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([ [-5, -7],[ 2, 0]], dtype=tf.float64)
# Printing the input tensor
print('a: ', a)
# Calculating result
res = tf.math.special.fresnel_cos(a)
# Printing the result
print('Result: ', res)
输出:
a: tf.Tensor(
[[-5. -7.]
[ 2. 0.]], shape=(2, 2), dtype=float64)
Result: tf.Tensor(
[[-0.56363119 -0.54546709]
[ 0.48825341 0. ]], shape=(2, 2), dtype=float64)
示例 2:
# importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([1, 2, 3, 4, 5], dtype=tf.float64)
# Printing the input tensor
print('a: ', a)
# Calculating result
res = tf.math.special.fresnel_cos(a)
# Printing the result
print('Result: ', res)
输出:
> a: tf.Tensor([1. 2. 3. 4. 5.], shape=(5,), dtype=float64)
>
> Result: tf.Tensor([0.7798934 0.48825341 0.60572079 0.49842603 0.56363119], shape=(5,), dtype=float64)
