It makes the messages shorter and IMO easier to read. >> thanks a lot. >> imfreehand is not selecting the region. it gives error like........ >> >> Error in ==> roiParseInputs at 29 >> iptchecknargin(low,high,nargin_client,client_name); >> >> Error in ==> imfreehand at 166 >> [commonArgs,specificArgs] = >> roiParseInputs(1,5,varargin,mfilename,{'Closed'}); >> >> Error in ==> freehandarea at 21 >> hFH = imfreehand(); I believe we recently had a thread that touched upon this issue. See message 6 in this thread: http://www.mathworks.com/matlabcentral/newsreader/view_thread/286157 > also i am calculating area of object using bwarea. it gives in format > 4.5299e+004. can i change its format so that it display 45299. actually i > am new in matlab.i dont know every commond. Change the display format of numbers in MATLAB using the FORMAT function. I usually use "format long g" personally. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com |
