How to get for/while loop to continue loop around?

Just to explain my code - I want it to initially satisfy until the height in the feed tank (hfinitial > 0), but then it has the first for loop (for pumping) and the second for loop (for refill). I can only get this to go through each loop once. Can I get it to repeat this for loop a number of times? Do I need to use a different statement e.g. if/while? Code is as follows;

Pi=300000;
g=9.81;
RHO=1400;
Po=101325;
Dt=0.05;
At=pi*(Dt.^2)/4;
Df=6.096;
Af=pi*(Df.^2)/4;
Dpc=1;
Apc=pi*(Dpc.^2)/4;
Cd=0.975;
Cp=0.7;
hpc=1.71;
hinitial=1.71;
hfinitial=6.096;
%All details up to this point must be input by user
%Calculation of further initial conditions
Ptinitial=RHO*g*hfinitial;
Qiinitial=Cd*At*sqrt((2*(Pi+(RHO*g*hinitial)-Ptinitial)/RHO));
Qoinitial=(At/(sqrt(1-Cp)))*sqrt(2*((Pi-Po)/RHO));
QHinitial=Qoinitial-Qiinitial;
Qrfinitial=Cd*At*sqrt(2*g*(hfinitial-hinitial));
tpinitial=sqrt(2/g)*(Apc/(Cd*At))*(hpc/(2*sqrt(((Pi-Ptinitial)/(RHO*g))+(hpc/2))));
trfinitial=sqrt(2/g)*(Apc/(Cd*At))*(hpc/(2*sqrt(hfinitial-(hpc/2))));
%n is the number of loops of if statement
%Assigning an empty matrix for all values to be calculated
RFDoutput=zeros(117,9);
t=1:117;
RFDoutput(:,1)=t;
RFDoutput(1,1)=0;
RFDoutput(1,3)=hinitial;
RFDoutput(1,2)=hfinitial;
RFDoutput(1,4)=Ptinitial;

t=1;
while((round(t0) <= t) && (t< round(t0+tpinitial))) & (0 < hinitial < 1.71) ;   %could put as if/while statement, while tinitial=<t<tpinitial
   RFDoutput(t+1,1)=t; %Input into matrix
   hdecH(t)=Qiinitial/Af; %Input into matrix
   hdecpc(t)=Qiinitial/Apc;
   hnewH(t)=hfinitial-hdecH(t);
   RFDoutput(t+1,2)=hnewH(t);
   hnewpc(t)=hinitial-hdecpc(t);
   RFDoutput(t+1,3)=hnewpc(t); %Input into matrix
   hinitial=hnewpc(t);
   hfinitial=hnewH(t);
   Pt(t)=RHO*g*hnewH(t);
   RFDoutput(t+1,4)=Pt(t); %Input into matrix
   Qi(t)=Cd*At*sqrt(2*((Pi+(RHO*g*hnewpc(t))-Pt(t))/RHO));
   RFDoutput(t+1,5)=Qi(t); %Input into matrix

     Qinitial=Qi(t);
     QH(t)=Qoinitial-Qi(t);
     RFDoutput(t+1,8)=QH(t);

     tpintitial(t)=sqrt(2/g)*(Apc/(Cd*At))*(hpc./(2*sqrt(((Pi-Pt(t))./(RHO*g))+(hpc./2))));
     z=round(tpinitial)+1;
     RFDoutput(t0:z,6)=round(tpinitial);

      trfinitial(t)=sqrt(2/g)*(Apc/(Cd*At))*(hpc./(2*sqrt(hfinitial-(hpc./2))));
      RFDoutput(t+1,9)=trfinitial(t);
      trfinitial=trfinitial(t);

     t=t+1;
  end
  while((hinitial < 1.71)&(round(tpinitial)+round(t0)+1 < t <= round(tpinitial)+round(t0)+1+round(trfinitial)))   %hover over to see matri dims. Some are matrices some are 1 value??

     RFDoutput(t+1,1)=t;
     hdecH(t)=Qrfinitial/Af;
     hnewH(t)=hfinitial-hdecH(t);
     hfinitial=hnewH(t);
     RFDoutput(t+1,2)=hnewH(t);

    hincpc(t)=Qrfinitial/Apc;
    hnewpc(t)=hinitial+hincpc(t);
    hinitial=hnewpc(t);
    RFDoutput(t+1,3)=hnewpc(t);

     Pt(t)=RHO*g*hfinitial;
     RFDoutput(t+1,4)=Pt(t);

      Qrf(t)=Cd*At*sqrt(2*g*(hfinitial-hinitial));
      RFDoutput(t+1,7)=Qrf(t);

      tinitial=t;
      t=t+1;
      t0=tpinitial+t0+trfinitial+2;

If you want to repeat both/one of your "while" loops, you can use "while" or "for" commands around your existing loops.

In other words, you can modify your MATLAB script as shown below:

for i = 1:<number of times you want to repeat>

< your while loop1>

< your while loop2>

end
