Returning a matched group in Matlab
— Kaushal ModiIn Matlab, the groups that are defined in parentheses are saved as tokens.
Here is a example where I am retreiving the first matched group or token.
string = 'adcout1_TAG_i.txt';
[tok] = regexp(string, '([^_]+).*[iq]\..*', 'tokens');
datapath_point = char(tok{1}); % convert cell to string
% returns 'adcout1' (without quotes)
Note that ’tokens’ argument to the Matlab regexp function makes that function
return a cell of tokens. In the above example that is stored in tok
cell. In
order to use that cell element as a string, I need to first convert it to a
string using the char
function.
