Function mle_evals_to_coeffs_inplace 

pub fn mle_evals_to_coeffs_inplace(
    evals: &mut DeviceBuffer<F>,
    n: usize,
    device_ctx: &GpuDeviceCtx,
) -> Result<(), CudaError>

Assumes that evals is column-major matrix of evaluations on a hypercube H_n. In-place interpolates evals from evaluations to coefficient form.
