Thank you very much.
In this site I have found many component or unit which can evaluate string expression.

But really i want to make a program which user can input his differential equation ,initial condition, for example
 x' = 2*x + 3u;
then i can use this equation to calculate x at any time

Could you give me for more idea ??
