To find minimum of a variable

Pls can you modify the below code

function Y = myFunc(P,P0) N = 2; Pa = 9;

k = floor((P0*N/Pa));

Y = F(P)+k*F(N*P0-P*k);

function Fp = F(P)

R = 3;

beta = 8;

Fp = 1 - exp(-((2^R-1)./P).^(beta/2));

%Step 2: Minimize it within the bounds:

P0 = 7;

[Pi, FVal] = fminbnd(@(x) myFunc(x,P0),0,1.1);

Pls modify the code such that P and P0 is as mentioned below

wherein P0 varies from 1 to 10 and P = [0, Pb]∪ ((N*P0)/(k+1))....( ∪ refers to union here)
