Hi, I am getting an error when I use webread, but only on certain machines and in certain versions. What other things should I check?

I get this problem with Windows 10, Matlab R2017b, Windows 7 Matlab R2017b and R2018a

    url = 'http://www.mathworks.com/matlabcentral/fileexchange';
     searchTerm = 'sensor-data-acquisition';
     html = webread(url,'term',searchTerm)
    Error using webread (line 119)
    Expected input to be a vector.

But it succeeds with Windows 10, Matlab R2018a

url = 'http://www.mathworks.com/matlabcentral/fileexchange';
searchTerm = 'sensor-data-acquisition';
html = webread(url,'term',searchTerm)}
html =
    '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
     <html lang="en">

end

I have just solved my own problem ... in my case, I had an old version of strjoin.m in my path above the newer R2018b version ... I removed the offending version from the path and it now works for me ... perhaps you have a similar problem? Good luck ...

It turned out to work on my Linux box. I guess I must have some conflicting script in my PC path that I haven't found yet. I'll look at strjoin. Thanks for the suggestion!
