ReadUI
- ReadUI(files, path, freq, varargin)
Full definition:
function UI = ReadUI(files, path, freq, varargin)
read current and voltages from multiple files found in path
returns voltages/currents in time and frequency-domain
remarks on the frequency-domain:
all signals are assumed to start at t=0
currents that e.g. start at t = +delta_t/2 will be phase shifted by exp(-jwt(1))
optional parameter:
freq: frequency-domain values will be calculated according to ‘freq’ if ‘freq’ is not given, a (zero padded) FFT will be used
optional key,value pairs:
‘AR’ : auto-regressive model to improve FD accuracy values: order to use within an AR model or ‘auto’
examples:
U = ReadUI({'ut1_1','ut1_2'},'tmp' );
I = ReadUI('it1' ,'tmp',[0.5e9 1e9 1.5e9]);
% using the auto-regressive model
U = ReadUI('port_ut1' , 'tmp', 'AR', 'auto');
