用matlab编写的无约束优化的源码，经过调试，都能运行，对数学建模竞赛帮助很大。(Prepared using matlab optimization of the source, through commissioning, to run on the Mathematical Contest in Modeling of great help.)

An orifice, through which hydraulic fluid flows, has a specially shaped inlet and exit in an attempt to minimize losses. During tests the measured variations of mass flow rate q with pressure drop (p1-p2) across the orifice yield the data shown below. (a) From these data estimate the orifice loss coefficient c0 (b)plot the flow v.s. pressure drop curve with the estimated c0 to validate your estimation.
