Error using ==> horzcat CAT arguments dimensions are not consistent. Listen I am not expert, This is my second week with Matlab.

Error using ==> flipdim at 21 > Requires two arguments. That is correct. If you look at "help flipdim" you will not see any examples of a 1-input syntax for that function. FLIPDIM requires exactly two inputs -- otherwise how would it know which dimension to flip or the array whose dimensions it should flip? When using a function that's new to you or one that you're not _entirely_ sure how to use, I strongly recommend reading through the function help (using the HELP function) and/or the documentation (using the DOC function.) Most of the functions include examples of their use in their help or documentation, and you can use these examples to make sure you're using the function correctly. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ
