How can I run this calculation multiple times?
c1 = 40 - 10;
c2 = 40 + ((600/210) + (275/21));
c = c1 + rand * (c2 - c1);
fck = 26 + rand * (34-26);
b1 = 300 - ((300/50)+7);
b2 = 300 + ((300/50)+7);
b = b1 + rand * (b2 - b1);
h1 = 600 - ((600/140)+(85/7));
h2 = 600 + ((600/140) + (85/7));
h = h1 + rand * (h2 - h1);
qb = 9.9775+rand *(10.0225-9.9775);
qs1 = 24.9775+ rand * (25.0225-24.9775);
ns1 = 2;
qs2 = 13.9775+ rand * (14.0225-13.9775);
ns2 = 2;
q1 = 0.8*1.5;
q2 = 1.4 * 1.5;
q = q1 + rand * (q2 - q1);
med = 96 * (10^6)+ rand * (144 * (10^6) - 96 * (10^6));
Es = 200000;
fyk = 500;
fcm = fck + 4 +rand * (12 - 4) ;
Ecm = 22000*((fcm/10)^0.3);
Ec = Ecm / (1 + q);
alpha = Es / Ec;
d1 = c + qb + (qs1/2);
d2 = c + qb + (qs2/2);
d = h - d1;
As1 = (pi * ns1 * (qs1^2))/4;
As2 = (pi * ns2 * (qs2^2))/4;
Astot = As1 + As2;
x = ((-alpha *Astot)/b)+ sqrt(((alpha*Astot/b)^2)+((2*alpha*(As1*d+As2*d2))/b));
fctm = 0.3 * (fck ^(2/3));
I = ((b*(x^3)/3))+ alpha * As1*((d-x)^2)+ alpha * As2*((x-d2)^2);
sigmac = med*x /I;
sigmas = alpha * sigmac * (d-x)/x;
h1 = (h-x)/3;
h2 = 2.5*(h-d);
h3 = h/2;
H = [h1 h2 h3];
Aceff = b*min(H);
rhoeff = As1/Aceff;
Srmax = 3.4 * c + 0.17* qs1 / rhoeff;
epsilon1 = 0.6*sigmas/200000;
epsilon2 = (sigmas / 200000)-(0.4*fctm*(1+alpha*rhoeff)/(rhoeff*200000));
epsilon = max(epsilon1,epsilon2);
wk = Srmax*epsilon

for i=1:N
_your code goes here_
end
N denotes the number of times your code is going to be operated.
