Dear all
I'm testing DCM for induced responses in my data set (EEG, 1 trial epoch, 256 Hz sampling rate, 64 channels, two dipole locations, freq. from 4 to 30 Hz). I'm using SPM12 r6906 on Matlab R2016a
When I try to invert the model, the code stops after the evaluation of the last frequency band and Matlab prompts: Undefined function or variable 'ey'. Can somebody tell me what this means and how I can resolve this issue?
Thanks,
Eugenio
