A common error with reshape() is that users attempt to reshape a matrix to a form where the number of elements is different. You'll get an error of the following: ??? Error using ==> reshape To RESHAPE the number of elements must not change. But again, you need to give people enough information to help you. Wayne

Error using ==> flipud at 19 X must be a 2-D matrix.

Note: please don't ask half your question in the subject line of the post and the other half in the body. It's okay (and even recommended) for the subject to contain a 'teaser', but even if you do that you should put the entire question in the body. So assuming your question was "Can anybody tell me what is wrong in this line imagesc(flipud(reshape(concentration, nx, ny, nz)));" the error message you should have received should have made it clear what's wrong in the line of code you posted above (assuming nz is not equal to 1.) Use FLIPDIM instead of FLIPUD, and make sure that the reshaped, flipped concentration array is in a format IMAGESC recognizes (which I believe means nz must be either 1 or 3.) -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ

Error using ==> flipdim at 21 Requires two arguments.
