function varargout = strfindb(txt,pattern)
%STRFINDB   Find string within cellstr.
%
%   b       = strfindb(cellstr,pattern)
%   [b,ind] = strfindb(cellstr,pattern)
%
% returns boolean matrix b (and indices matrix ind) of 
% cellstr that have a (one or more) matches of pattern.
%
% Note: case sensitive.
%
% Example:
%
%   ind = strfindb({'aa','ab','bb'},'a') % is [1 1 0]
%   ind = strfindb({'aa','ab','bb'},'A') % is [0 0 0]
