Srry, it was a typo. What I meant to say is that even if the file says true, and it reads in true, the strcmp doesn't figure that out and always returns false.

well...
then you're not telling the whole story(!)...

v1='true';
v2={'true'};
r={
strcmp(v1,'true'),strcmp(v1,'false')
strcmp(v2,'true'),strcmp(v2,'false')
};
disp(r);
%{
[1] [0]
[1] [0]
%}

You need to be more specific in what you post. According to everything you say, your code should of course work. Try this code and post the result here:

% note: no semicolons. show all the output
constantPath_str = textscan(fid1, '[%s]\n', 'CommentStyle', '%', 'delimiter', ']')
constantPath_str=constantPath_str(1)

class(constantPath_str) % note: added line

boolcheck=strcmp(constantPath_str, 'true')

if boolcheck==1
constantPath=1
else
constantPath=0
end

isequal(boolcheck, constantPath)
% this last line should return 1
% so you don't actually need the intermediate boolcheck
