every time I use createMask I get this error "Too many output arguments." what could be the problem ? I tried two examples in matlab documentation but still getting the same error
those are the examples
/////////////////////////
img = imread('pout.tif');
h_im = imshow(img);
e = imellipse(gca,[55 10 120 120]);
BW = createMask(e,h_im);
//////////////////////////
figure, imshow('pout.tif');
hpoly = impoly(gca);
BW = hpoly.createMask();
figure, imshow(BW);
thanks in advance

That worked fine for me.
What line is the error on?
More than likely you have some function shadowing one of the builtins. For example maybe gca
which -all gca
Use which -all on all the functions on the offending line and rename the offending function so that it does not shadow the MATLAB functions

when I used which -all gca I got built-in (C:\MATLAB\R2012b\toolbox\matlab\graphics\gca) what is this?

this is the error Error using getimage Too many output arguments.
Error in imroi/getPixelPosition (line 60) [xdata,ydata,a] = getimage(h_im);
Error in imroi/createMask (line 259) [roix,roiy,m,n] = obj.getPixelPosition(h_im);
Error in testmask (line 9) BW = createMask(h);
when I use which -all getimage I got this C:\MATLAB\R2012b\toolbox\images\imuitools\getimage.m % Shadowed
what should I do please?

So that is exactly it: getimage is shadowed.
What is the full output from
which -all getimage
There must be another one (MATLAB file or variable) if that one is being shadowed.

this is the full output from which -all getimage C:\Documents and Settings\am_jamal\My Documents\MATLAB\getimage.m C:\MATLAB\R2012b\toolbox\images\imuitools\getimage.m % Shadowed

how can I rename a built-in function? (getimage)
Amani
Amani 2013-5-23
thank you sooooooooooooooooooooo much , I got it and the probelm is fixed by changing the name of a m-file that created

Don't rename the builtin! Rename the one you wrote, i.e:
C:\Documents and Settings\am_jamal\My Documents\MATLAB\getimage.m
MATLAB expects the function getimage to be the one in the toolbox, when it's not you run into the type of error you're having. Rename your getimage.m to something else.
