Ive got some code from my tutor thats meant to be filtering a medical signal (ecc) by multiplication in the frequency domain, all goes well till Y5=X5.*HBR; , there it says matrix dimensions must agree, been rattling my head about this for a while but cant figure out where the conflict is, tutor wont help either.
set(gca, 'XScale', 'log')
medical = 'medical signal.dat';
HBC = fft(hb)/length(hb);
Any suggestions on whats causing the matrixes to conflict?
