Hey. I was writing a code to show efficiency of thermoelectric generators in one plot. tc is constant in each statement, first z changes and for each z, I want to plot a line based on the th variation. each line, for instance, z=0.5 and th from 300 to 1250 has a specific color for readability.
tc(1:20)=298;th=300:50:1250;figure;hold on;
for t=1:20
z(t)=t./4;
for i=1:20
etha(i)=((th(i)-tc(i))./th(i)).*((sqrt(1+((z(t).*th(i)+tc(i))./2))-1)./...
((sqrt(1+((z(t).*th(i)+tc(i))./2))-(tc(i)/th(i)))));
ln=plot(th(i),etha(i));
ln.Color=(1./t).*[1 1 1];
ln.LineWidth=2;
ln.Marker='*';
end
end
hold off
the output is like this
but I desire for an output like this
anyone has any suggestion? I know I'm amateur....

Might need some more tinkering - this is limited to 7 lines rather than the 20 you have in your code
tc(1:20)=298;
th=300:50:1250;
for t=1:7
z(t)=t./4;
for i=1:20
etha(t,i)=((th(i)-tc(i))./th(i)).*((sqrt(1+((z(t).*th(i)+tc(i))./2))-1)./...
((sqrt(1+((z(t).*th(i)+tc(i))./2))-(tc(i)/th(i)))));
end
end
ln=plot(th,etha,'*-','LineWidth',2);
