Hello, i'm a braziliam master's degree student in applied mathematics.
I found different results working with the eval function in versions 7.0 and 7.10 of Matlab, could you explain these differences?
I managed to circumvent the problem with small changes in my algorithm, but I wonder what changed. I thank you for your cooperation.

You should NOT be using eval.
It is an evil function that has no place in a student's repertoire.
Learn to avoid the evil eval and you will improve your coding skills
immensely.

Dear Adriano,

You forgot to mention any details of "the differences" or "the problem". EVAL can be used for calling any function and can be applied to do each and every dirty trick. I guess, that the change does not concern EVAL, but the called functions. So please be more specific and post the relevant source code lines.

Kind regards, Jan
