I should implement it one day
The function nodes_from_elecs
that extracts a list of unique nodes from a list of electrodes does not work as intended.
Algorithm as published in [1]. I probably messed the array indexing.

When downloading one of the releases, there is a cubature folder, but no files in it. The user must then manually donwload (or git clone). I should probably add its contents to the release to facilitate to the end user, but it is BIG (14 MB)...
There is a loop in the function laplace_trans
that assigns a complex value to a real array. That is a silent bug waiting to happen. Though, none of the examples calls this function or its inverse, they commit the exact same error.
double* in = fftw_malloc(nt * sizeof(double)); // real array
...
in[k] = f[k] * dt * cexp(-c * k * dt); // complex value
