Operator to upsample an operator by inserting zeros between values.

Template Parameters:

T – Input operator/tensor type

Parameters:

  • op – Input operator

  • dim – the factor to upsample

  • n – Upsample rate

Upsampled operator

Examples#

// Upsample a signal of length 100 by 5
int n = 5;

auto t1 = make_tensor<TestType>({100});
(t1 = static_cast<TestType>(1)).run(exec);
auto us_op = upsample(t1, 0, n);
