Assume that y' = y.t needs to solved i.e.one needs to find y(t) for the initial condition yo = 0.3. In your Math classes, you were taught how to solve this differential equation. However, most differential equations are not easily solvable, and one needs to resort to numerical integration. This can easily be done in MATLAB for explicit first order differential equations like the one stated above. The time of interest is between tstart
