How can you rewrite something, which src's is available without copying at least parts of the code (m-files)??? If there is a copyright on it than it is probably also on parts of it. Where is the border (how many loops, which variable names)? I think this is a VERY undefined region. Any ideas? When I want to rewrite a whole toolbox it should be at least 100% compatible +more features. Otherwise I have really big problems here whith the "productivity line" running on matlab. -- Mit freundlichen Gruessen Daniel Heiserer ----- -------------------------------------------------------------- Dipl.-Phys.
