This function calculates an inverse (orthonormal) discrete cosine
transformation for given coefficients in three dimensions using the
fftw3 (see http://www.fftw.org/). As many
coefficients are expected to be zero, the values are given in
compressed format (indices and values only of non-zero coefficients).
A numeric vector, containing the non-zero coefficients.
An integer vector, containing the indices of the non-zero coefficients.
A numeric vector of length 3, giving the resulting image dimensions.
A matrix of dimensions

combination of cosine tensor basis functions with the given
