torch_lerp: Lerp

Description

Lerp

Usage

torch_lerp(self, end, weight)

Arguments

self

(Tensor) the tensor with the starting points

end

(Tensor) the tensor with the ending points

weight

(float or tensor) the weight for the interpolation formula

lerp(input, end, weight, out=NULL)

Does a linear interpolation of two tensors start (given by input) and end based on a scalar or tensor weight and returns the resulting out tensor.

$$ \mbox{out}_i = \mbox{start}_i + \mbox{weight}_i \times (\mbox{end}_i - \mbox{start}_i) $$ The shapes of start and end must be broadcastable . If weight is a tensor, then the shapes of weight, start, and end must be broadcastable .

Examples

if (torch_is_installed()) {

start = torch_arange(1, 4)
end = torch_empty(4)$fill_(10)
start
end
torch_lerp(start, end, 0.5)
torch_lerp(start, end, torch_full_like(start, 0.5))
}
