It seems to be such an easy thing but I can't right remember
So, I've got an array of x values (2708x1) and y values(2708x1) and a function Amp(x). How to plot(Amp(x),y) ?

I guess I posed my question in the wrong way, I'll re-ask it. Thank you for your effort :)

Amp = @(x) 6.344*10^(-7)*x.^6 + 3.938*10^(-5)*x.^5 -0.001053*x.^4 -0.01953*x.^3 + 0.2699*x.^2 + -13.92*x + 502.4;
x = M{:,1};
y = M{:,2};
plot(Amp(x),y)
