Those are great suggestions, I didn't even think on that I have even one idea, since

MATLAB lacks of symbolic representation, I am thinking on solving an DE & then

export it into Maple with the Maple Toolbox for MATLAB, I just have to make that

thing work correctly, I guess it is going to probably look great.

Thanks any other suggestion is greatly appreciated, the presentation is going to be

next thursday, I'll let you guys know the details.
