I am using fgetl to read lines in a text file. Is there a way to detect whether one of the whitespace characters is a "tab" ?
Thanks in advance for your help.

istab=(l==9); % the fast way...
istab=strfind(l,char(9)); % the char() string string functions way

S = sprintf('abc\tdef'); %text with a tab in it
S == 9 %fast, simple, and tab character unlikely to change any year soon
strfind(S, sprintf('\t')) %just in case tab someday changes to a multi-character sequence
%unicode defines three additional tab-related functions
ismember(S, [0x09 0x0b 0x88 0x89 0x8a]) %HT VT CTS CTJ LTS
%unicode defines several tab symbols
ismemember(S, [0x09 0x0b 0x88 0x89 0x8a 0x2409 0x240b 0x21b9 0x21c6 0x21E4 0x21E5]) %HT VT CTS CTJ LTS various tab symbols
