flipud script problem

http://www.mathworks.com/matlabcentral/answers/1875-segmenting-using-x-y-co-ordinate-axis

I used the flipud function given in this answer earlier and it worked perfectly. Now for some reason everytime I try to execute this program or the version I have created of it, the interpreter stops at the 'axis xy' line. What could be the problem ?

[Matt Tearle]

what do you mean "stops"? an error? a breakpoint? it just doesn't seem to do what you expect the remaining lines to do?

If you are using this method, because it works for you (earlier), then it would be a good idea to accept the given answer in this thread.

Answer 1

[Paulo Silva]

axis is a matlab function and you gave your script the same name, when you do axis xy your are actually calling your own script instead of the matlab function, the error comes up because your script isn't a function thus not accepting arguments (xy).

[Matt Tearle]

Bingo. Solution: change the name of script to something other than axis.

Tip: before you save your script as foo.m, enter

which foo

in the Command Window to see if something called foo is already on the MATLAB path. If so, pick a different name.

Did you set a breakpoint? You can check this by:

dbstatus

??? Attempt to execute SCRIPT axis as a function:

Z:\home\siddharth\Documents\College Stuff\BE Project\Attempt1\axis.m

Error in ==> axis at 6

axis xy

This is the error I get
