Some of the arguments for using GBM to model stock prices are: The expected returns of GBM are independent of the value of the process (stock price), which agrees with what we would expect in reality. And with a little algebra, we can rearrange those equations to solve for ANY of the variables in them. MATLAB is an interactive, matrix-based system for scientific and engineering calculations. It has a mass of m = 0. 1) for and substituting into the r-equation (5.
