saveas error

Priya — Fri, 20 Nov 2009 23:44:19 -0500

Usually I am able to save images in matlab. However something unusual happened today, which I have not been able to figure out.

Here is in a example:

>> plot(1:10)
>> saveas(gcf, 'test.tiff')
??? Error: File: printopt.m Line: 1 Column: 25
The input character is not valid in MATLAB statements or expressions.

Error in ==> printjob at 70
[ pj.PrintCmd, pj.DefaultDevice ] = printopt; %Defaults

Error in ==> print at 166
pj = printjob;

Error in ==> saveas at 159
print( h, name, ['-d' dev{i}] )

Can someone please help me figure out what is wrong?

Thank you!

Dunno. It worked for me (Matlab r2007b, r2009a, and r2009b)

Strange.

I know, it used to work for me too earlier, but it is not anymore.

What does "which -all printopt" show?

Edit it and look at line 1, column 25. What character is in that position?

I had a similar problem and found a fix. In my case it was a conflict between too many printopt.m files lying in the path.

Steve Lord suggested examining "line 1, column 25" of, I assume, printopt.m. I tried this using "edit printopt.m" and saw garbage because MATLAB opened some other copy that had been installed in directory created by the MATLAB compiler. (The directory included something like "_mcr" or "_mcc") I removed these directories and the problem was solved.
