Mathematical modeling software is very extensive. I don't know what mathematical modeling software you are talking about. If there is such mathematical software, such as matlab, lingo, spss, there is definitely no mobile phone. These are very big, but there is a mobile phone version of matlab, or open the computer matlab. The mobile phone is connected to the computer. I have tried it directly this year, and it is useless.

There are many math softwares on the iPad, which are produced by wolfram. It seems to cost money, so I downloaded these two softwares on the iPad, which are basically unnecessary.

There are other modeling software, such as CAD and 3Ds MAX, so there can only be computers.
