Why this is happening?

[m n] = size(image);

I tried this command earlier and it worked well but now showing this:

"Indexing cannot yield multiple results."

Did you name one of your variables ‘size’ later in your code?

[VIJENDRA]

yes.. i clear that variable and the function works normally... Thanks for your reply

My pleasure!

It's also not a good idea to take the size of a built in function like image ()! Hopefully your image is not really named that!

And actually, even if it has a different name, that way of calling size() can be risky. Why? Read Steve's blog: http://blogs.mathworks.com/steve/2011/03/22/too-much-information-about-the-size-function/. Better, if you know it's not a multispectral image but is a regular indexed, RGB, or monochrome image is to do

[rows, columns, numberOfColorChannels] = size(yourImage);
