I am trying to write a code for multivariable fuction. I want all values of p2 and want to extract unique values.

The code is as follow

clear all
clc
format longEng
syms z y1
phi=(pi/180)*39;
delta=(pi/180)*26;
gma=18.4;
beta=2
h=2;
h1=2;
L=h+h1;
kh=0.0;
kv=0;
R2=3*(beta*(1-y1))^0.5
psi=atan(kh/(1-kv));
delm23=0.5*(3-1)*delta;
        k23=1+0.5*(3-1)*((cos(phi-psi)^2/(cos(psi)*(cos(delm23+psi)*...
            (-sqrt((sin(phi+delm23)*sin(phi-psi))/(cos(delm23+psi)))+1)^2)))-1)
         
        delm213=0.5*(R2-1)*delta
        k213=1+0.5*(R2-1)*((cos(phi-psi)^2/(cos(psi)*(cos(delm213+psi)*...
            (-sqrt((sin(phi+delm213)*sin(phi-psi))/(cos(delm213+psi)))+1)^2)))-1)
    
        delm201=0.5*(1-R2)*delta;
        k201=(2*cos(phi-psi)^2)/(cos(phi-psi)^2*(1+R2)+cos(psi)*cos(delm201+psi)...
            *(1-R2)*(1+sqrt((sin(phi+delm201)*sin(phi-psi))/cos(delm201+psi)))^2)
i=0;
for z=0:0.1:L
    i=i+1;    
 if(z<=h)
    p1(i)=0.2*z;
    p2(i)=0;
 else
       p1(i)=0.5*z;
       j=0;
     for y1=0:0.1:1
         
         j=j+1
      
         if (y1>=0 && y1<=(1-(1/beta)))
          p2(i,j)=-gma*(z-h)*k23*cos(delm23)
          
      elseif (y1>(1-(1/beta)) && y1<=(1-(1/(9*beta))))
             p2(i,j)=-gma*(z-h)*eval(subs(k213*cos(delm213)))
      
      else 
           p2(i,j)=-gma*(z-h)*eval(subs(k201*cos(delm201)))
      end
     end
 end
end
z=0:0.1:L;
% subplot(2,1,1);
plot(p1,z,p2,z)
grid on
set(gca, 'YDir','reverse')
