Function efd::inverse_transform

pub fn inverse_transform<'a, A>(
    coeffs: A, 
    (lx, ly): (f64, f64), 
    n: usize, 
    harmonic: Option<usize>
) -> Array2<f64> where
    A: AsArray<'a, f64, Ix2>, 

Perform an inverse fourier transform to convert the coefficients back into spatial coordinates.

The argument harmonic is optional, defaults to the row number of coeffs.
