Write a MATLAB script to calculate and plot a sequence of 50,000 points, as defined in the question below. A sequence of points is generated by starting at (x0,y0)=(0,0) and then generating the next point to be (xi+1,yi+1)=fj(xi,yi), where j is chosen randomly each time to be 1,2 , or 3 . The three functions are given as follows: f1(x,y)=(ax,by)f2(x,y)=(ax+c,by)f3(x,y)=(ax,by+d) Your four parameters are: (a,b,c,d)=(0.53,0.51,0.43,0.54)
