how to search by a word in three or four columns if exist record this column
i use a code which search in one column only
so i have to search by the same word three times each time in a different column
i use this code
for E=1:R % from 1 : length of columns
B=~cellfun('isempty',regexp(D,'power')) ; % works good search for power and return 1 or 0
if (B(E) == 1) % if value of array greater than or equal 1
Defs(j)=E; % save its postion (E,1)
j=j+1;
else % save all arrays didn't have 'power' separately
