Using strcmp with multiple inputs

Hello everyone,

I have a question, I want to use strcmp but for multiple inputs. For example if this row contain THIS or THAT.

This is what I'm using

B = find(strcmp(rw(:,3),' Dr limited' ));

what I want

B = find(strcmp(rw(:,3),'Dr limited' | 'Dr Limited' ));

because sometimes it can be a capital or the last name changes. So I want to know if I can put all the possibilities and get where to find them. Or even put the word 'Dr' the get the locations.

Thank You!

You could use strfind or a regular expression to help you, e.g.:

>> ixc = cellfun(@ischar,rw(:,3));
>> ixc(ixc) = ~cellfun('isempty',regexpi(rw(ixc,3),'Boskalis','once'));
>> idx = find(ixc)
idx =
     1
    58
   108

You can use strcmpi, which is a non-case-sensitive version of strcmp.

B = find(strcmpi(rw(:,3),'boskalis westminster dredging limited'));

Also, if you are trying to determine which rows of rw contain this string, the use of find may not be the most efficient method. Try considering the following.

% Since strcmp and strcmpi return a boolean array, you can use that result as an index and extract only
% the rows matching your specified string.
B = rw(strcmpi(rw(:,3),'boskalis westminster dredging limited'),:);

Additionally, if you are trying to match one of multiple strings to a given string you can do so by using a cell-array of specified strings.

B = any(strcmp(rw(:,3),{'Boskalis Westminster Dredging limited','Boskalis Westminster Dredging Limited'}));
