MATLAB: STRCMP in a loop

Question

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()
