mindsponge.common.vecs_scale

mindsponge.common.vecs_scale(v, scale)

Scale the vector.

$$\begin{array}{r}\begin{array}{rl}& v=(x1,x2,x3)\\ & scaled\mathrm{\_}vecs=(scale\ast x1,scale\ast x2,scale\ast x3)\end{array}\end{array}$$

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)
