In order to solve the calculation problem in detonation and extinction simulation of smoke munitions and provide a directly data analyse of correlative parameters which is used to describe detonation and extinction of smoke munitions, matlab/GUI is used in this paper by which we finish to evaluating those parameters because of the strong calculating capability of Matlab and draw the movement trace of smoke munitions detonation with the functions provided by Matlab. A nicer interactive GUI is designed offering intuitionistic data to study concerned parameters of smoke Munitions in different situation such as with different format and different quantity. Empirical show the result is nearly accurate,.exe files producted from GUI are transplantable, they can also be executed out of the Matlab environment which can be widely used in other program, in other words the.exe files support for the further integration, so we can use this method effectively to solve the conflicts of the complicated numerical calculation.
