Check any string from a set of substrings available in main String in MATLAB

Question

We have set of sub strings t = (b6,b7,y7,y8) and a main String K ='hgtb6ju\u'.

I need to check whether any of the element in t available in K. If yes, which substring(s).

Answer 1

t = {'b6', 'b7', 'y7', 'y8', 'ju'};
K = 'hgtb6ju\u';
logidx = ~cellfun(@isempty,regexp(K,t)); %Finding if substrings are present
matched = t(logidx)  % Finding which substrings are present
