I AM WRITTINF THIS CODE AND GETTING THE FOLLOWING WARNING

clc 
clear all 
u= imread('b.jpg'); 
A=rgb2gray(u);  

Warning: Function image has the same name as a MATLAB builtin. We suggest you rename

the function to avoid a potential name conflict.

[Torsten]

Did you name one of your functions "image.m" ? Then you should rename it since it conflicts with the MATLAB function:

@Torsten no, i used the function name "image". but then i changed it . but still it is showing warning

Check this again:

which image -all

Is there a user-defined function in the list?

If not, clear all should solve the problem already. But maybe a restart of Matlab helps also.
