mindspore.mint.cos
- mindspore.mint.cos(input)[源代码]
逐元素计算输入tensor的余弦。
警告
如果使用float64,可能会存在精度丢失的问题。
- 参数:
input (Tensor) - 输入tensor。
- 返回:
Tensor
- 支持平台:
Ascend
样例:
>>> import mindspore >>> # The data type of output will be float32 when `input` is in [bool, int8, uint8, int16, int32, int64]. >>> input = mindspore.tensor([0, 1, 2], mindspore.int32) >>> mindspore.mint.cos(input) Tensor(shape=[3], dtype=Float32, value= [ 1.00000000e+00, 5.40302306e-01, -4.16146837e-01]) >>> >>> # Otherwise output has the same dtype as the `input`. >>> input = mindspore.tensor([0.74, 0.04, 0.30, 0.56], mindspore.float64) >>> mindspore.mint.cos(input) Tensor(shape=[4], dtype=Float64, value= [ 7.38468559e-01, 9.99200107e-01, 9.55336489e-01, 8.47255111e-01])
