Piecewise functions are sometimes useful when the relationship between a dependent and an independent variable cannot be adequately represented by a single equation. For example, the velocity of a rocket might be described by:v(t)= 10t^2 -5t 0<= t< =8 624- 5t 8<= t<= 16 36t+12(t-16)^2 16 <= t <= 26 2136e^-0.1(t-26) t> 26 0 OtherwiseDevelop an M-file function to compute v as a function of t .
