    Matlab function

    Hi, i'm new to this software and need help with the following question:

    The vectors x and y represents two dependent measurements. Try to identify (i.e., determine function coefficients a,b,c,d, and p) this dependency by utilizing the following three model function defined by y1, y2, y3.

    y1 = a(x^b)
    y2 = c.e^(dx)
    y3 = p1.(x^n) + p2.x^(n-1) +...+ pn.x + p(n+1) (order n<=5)

    i know how to do the 2 first ones, but being stuck with the third
    thanks
