由OUADDEMO、ZERODEMO和FPLOTDEMO等函数调用的一个函数

humps(x)是一个在x=0.3和x=0.9附近有尖锐极大值的函数

[X,Y]=HUMPS(x)在无输入时，HUMPS将使用x=0:0.5:1返回X-By the OUADDEMO, ZERODEMO and FPLOTDEMO other function calls a function　humps (x) is an x ​ ​ = 0.3 and x = 0.9 the maximum value near the sharp function　[X, Y] = HUMPS (x) in the absence of input , HUMPS uses X return x = 0:0.5:1
