Data hiding Matlab

I gave the binary message as 01101001 format and input as 6*6 image. But getting error as index exceeds matrix dimensions in the below line. stegoI(i:i+2,j:j+2)=embed(I(i:i+2,j:j+2),message(indexm:indexm+1)); Can you please clarrify my doubt. Thank you

Please post the relevant part of the code. It is not possible to guess, if "embed" is a matrix or a function. E.g. "message" could be shorter than "imdexm+1" etc.

A recommended method to solve such problems is the debugger:

dbstop if error

Then MATLAB stops, if the error occurs and you can inspect the values of the variables to find the cause of the problem. This is more efficient than asking the forum.
