mindsponge.common.vecs_scale

mindsponge.common.vecs_scale(v, scale)[source]

Scale the vector.

\[\begin{split}\begin{split} &v=(x1,x2,x3) \\ &scaled\_{vecs} = (scale*x1,scale*x2,scale*x3) \\ \end{split}\end{split}\]

Parameters

v (Tuple) – Vector will be scaled, \((x,y,z)\). x, y, z are scalars or Tensor with same shape.
scale (float) – Value of scale.

Returns

Tuple with length of 3, vector after scaled with the same shape as input v.

Supported Platforms:: Ascend GPU CPU

Examples

>>> import numpy as np
>>> from mindspore import Tensor
>>> from mindspore import dtype as mstype
>>> from mindsponge.common.geometry import vecs_scale
>>> x= Tensor(np.ones(256), mstype.float32)
>>> y= Tensor(np.ones(256), mstype.float32)
>>> z= Tensor(np.ones(256), mstype.float32)
>>> scale=10
>>> result=vecs_scale((x,y,z),scale)
>>> print(len(result))
>>> print(result[0].shape)
>>> print(result[1].shape)
>>> print(result[2].shape)
