% if you want to use with timer %% create a timer %%% create a new file with following code and name it as main .

global indx indx=1; showTimer=timer('timerFcn',@slideshow); set(a,'ExecutionMode','fixedRate'); set(a,'Period',2) %% 2 sec delay start(a)

%%% create a function function slideshow(varargin) global indx imgNameList= char('img1.tif','img2.tif','img3.tif'); indx=indx+1; if indx> length(imgNameList) indx=1; end imshow(a); drawnow;

%%% Now run main file

how can i run this code i mean it has error do i write this code in main.m file? %%% create a function function slideshow(varargin) global indx imgNameList= char('img1.tif','img2.tif','img3.tif'); indx=indx+1; if indx> length(imgNameList) indx=1; end imshow(a); drawnow;

what is the error?

[Shivaputra Narke]

You have two create two files. one that is your main file normal script other is function file.

create a new file and save it as slideshow and enter following code

function slideshow(varargin) global indx imgNameList= char('img1.tif','img2.tif','img3.tif'); indx=indx+1; if indx> length(imgNameList) indx=1; end imshow(a); drawnow;

%%% End of function %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Now create new file and save it as you want with following code,

global indx indx=1; showTimer=timer('timerFcn',@slideshow); set(a,'ExecutionMode','fixedRate'); start(a)

[romasha]

i did as u said but there is an error

Error: main Undefined function or variable 'a'.

Error in main (line 3) set(a,'ExecutionMode','fixedRate');
