lerp

paddle. lerp ( x, y, weight, name=None ) [source]

Does a linear interpolation between x and y based on weight.

Equation:
\[lerp(x, y, weight) = x + weight * (y - x).\]
Parameters
  • x (Tensor) – An N-D Tensor with starting points, the data type is float32, float64.

  • y (Tensor) – An N-D Tensor with ending points, the data type is float32, float64.

  • weight (float|Tensor) – The weight for the interpolation formula. When weight is Tensor, the data type is float32, float64.

  • name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

An N-D Tensor, the shape and data type is the same with input.

Return type

out (Tensor)

Example

import paddle

x = paddle.arange(1., 5., dtype='float32')
y = paddle.empty([4], dtype='float32')
y.fill_(10.)
out = paddle.lerp(x, y, 0.5)
# out: [5.5., 6., 6.5, 7.]
