using matlab

3. Piecewise math functions are useful when the relationship between a dependent and an independent variable cannot be represented by a single equation. For example, the velocity (v) of a rocket as a function of time (t) might be described by 11t2 5t 0 30 0 otherwise 1700e-0.2(t-30) Develop and write a Matlab function m-file that computes v as a function of t (taking t as the input argument and returning v as the output argument). Write a wrapper program using a script m-file that gets a value of time from the user, applies the function, and outputs the velocity to the screen
