I have been trying to use following functions but it comes up with error message. 

duration =0.05; % 10ms for BAEP, 500ms for P300, 250ms for EEG, 50ms for SSEP
samples = 640; %500  or 1000 samples (plus defined centrepoint)
samplingInterval = duration/samples;
bandwidth = 3e3;% 3kHz -BAEP & SSEP , 200Hz - EEG & P300, 

time = linspace (0, duration, samples);
freq = linspace (-bandwidth, bandwidth, 640);
% freq = linspace (-1.0e3, 1.0e3, 500);alternative baseline
fourierSpace = fftshift(ifft(norm_relbow_motor1a));
plot (freq, abs(fourierSpace))


Undefined function or variable 'norm_relbow_motor1a'.

When I tried with F9 function Key it came up with following error message.
Undefined function 'Undefined' for input arguments of type 'char'

Is anyone can who can help me in this regard, I will highly appreciate.

Regards

Kim

This is the same problem with likely the same solution as the other -- 
you've not got the data loaded yet.
