Algorithm for fitting complex-valued PARAFAC (CPD) model

Do you want to fit a PARAFAC model with complex values? For example to complex data. But it could also be to real-valued data. We made an algorithm way back in 2000

You can find the MATLAB algorithm here – maybe it works – it’s been a while!
