I'm trying to correct this line ploting using interpolate method .
but seem blocky shape appears
the coding in the body
function [TI1,TI2,TI3] = ER_Function
er1=(1+1.8*10^14*1i);
er2=(2.5+2.5*10^-3*1i);
Hc=(10^6);
H1=(0);
P1= 0:0.02:0.30;
Pc=(0.33).*exp((-(H1)/Hc));
c1=(1-3*Pc).*(((P1)./(Pc)).^Pc).*(((1-P1)./(1-Pc)).^(1-Pc));
T1=(1./(2.*(2+c1))).*(((3*P1-1+c1)*er1+(2-3.*P1-c1)*er2)+(((((3*P1-1+c1)*er1+(2-3.*P1)*er2).^2)+(4.*(er1).*(er2).*(1-c1).*(2+c1))).^0.5));
PI1=[0,0.20,0.23,0.25,0.27,0.30];
TI1= spline (P1,T1,PI1);
P2= 0:0.02:0.30;
er1=(1+1.8*10^14*1i);
er2=(2.5+2.5*10^-3*1i);
Hc=(10^6);
H2=(10^6);
Pc=(0.33).*exp((-(H2)/Hc));
c2=(1-3*Pc).*(((P2)./(Pc)).^Pc).*(((1-P2)./(1-Pc)).^(1-Pc));
T2=(1./(2.*(2+c2))).*(((3*P2-1+c2)*er1+(2-3.*P2-c2)*er2)+(((((3*P2-1+c2)*er1+(2-3.*P2)*er2).^2)+(4.*(er1).*(er2).*(1-c2).*(2+c2))).^0.5));
PI2=[0,0.20,0.23,0.25,0.27,0.30];
TI2= spline (P2,T2,PI2);
P3= 0:0.02:0.30;
er1=(1+1.8*10^14*1i);
er2=(2.5+2.5*10^-3*1i);
Hc=(10^6);
H3=(2*10^6);
Pc=(0.33)*(exp(-H3/Hc));
c3=(1-3*Pc).*(((P3)./(Pc)).^Pc).*(((1-P3)./(1-Pc)).^(1-Pc));
T3=(1./(2.*(2+c3))).*(((3*P3-1+c3)*er1+(2-3.*P3-c3)*er2)+(((((3*P3-1+c3)*er1+(2-3.*P3)*er2).^2)+(4.*(er1).*(er2).*(1-c3).*(2+c3))).^0.5));
PI3=[0,0.20,0.23,0.25,0.27,0.30];
TI3= spline (P3,T3,PI3);
J=plot ( PI1, real(TI1),'r',PI2, real (TI2),'g',PI3, real (TI3) , 'b');
J(1).LineWidth = 2;
J(2).LineWidth = 2;
J(3).LineWidth = 2;
title('Magnetic Field' ),xlabel('(P) concentration Volume'),ylabel('\bf\epsilon^e','FontSize',20)
legend({'H1=0','H2=10^6','H3= 2*10^6'},'Location','northwest','NumColumns',3)
end

It's presumably because you have not chosen your query points to be very close together. Do you get something closer to what you expect if you define something like
PI3=[0:0.002:0.30];
