obj = findInstrument('STR') returns an interface object to an instrument whose model name, vendor name or VISA resource matches any part of the string STR.
findInstrument requires the Instrument Control Toolbox™ and a VISA adaptor, and currently only works with USB and GPIB instruments.
(See the published MATLAB file for sample outputs)
% see a list of all the available instruments
% find an instrument by model number
obj = findInstrument('34405');
% find an instrument by model number, using Agilent VISA
obj = findInstrument('34405', 'agilent');
% find an instrument by model number and
% create a device object
obj = findInstrument('33120');
fgen = icdevice('agilent_33120a.mdd', obj);
% find an instrument by matching a manufacturer name
obj = findInstrument('tek');
% find an instrument by the model code in the VISA resource
obj = findInstrument('0x0618')
Helpful example for me to use the Instrument Control Toolbox.
By the way, is "%#ok<CTCH>" just purely a comment in the try catch block or it actually means something ?
Also, when there is an error thrown, should the function returns instead of continuing ?
If you add a dot to the regexpi line "(?<resource>[A-Z0-9:.]+)" it is also recognising TCPIP VISA resources. (constructor=visa('ni', 'TCPIP0::192.168.1.1::inst0::INSTR');
