STRCMP in a loop

I have a variable number of strings stored in an array. I want to compare each of those strings with a cell, and if the cell does not match any of the strings in the array, I want to delete it.
I'm not quite sure of the syntax. I know I can find the number by using length, but I can not do something like:
for j=1:length(match)
for i=1:length(compare_strings)
if strcmp(compare_strings(i),match(j))==0
compare_strings(i)=[];
end
end
end
It need to be more along the lines of:
if (strcmp(compare_strings(i),match(1))==0 && strcmp(compare_strings(i),match(2))==0 && strcmp(compare_strings(i),match(3))==0)
compare_strings(i)=[];
end
I need to check all of them at once, otherwise I may delete something that doesn't match the first, but matches one of the next. Any thought on the approach?

Use ismember()

You can also use strcmp() with cell strings which will eliminate the loop. http://www.mathworks.com/help/matlab/ref/strcmp.html

Look at this example
first_liste={'vert','jaune','rouge','azure','bleu'}
second_liste={'verte','noire','cerise','rouge','bleu'}
[ii,jj]=ismember(first_liste,second_liste)
second_liste=second_liste(jj(jj>0))
