```Thank you , Allen

Actually I have written wrong values in the range of for loop. Now my graph
is plotted. But not exactly that I want. I am new for Octave and I have
plotted  very simple graph. That way I am facing problem. Now I  modify the
code as you suggest. see:

function k=value(doverA,aoverA)
up=(1-(aoverA)^2-(2*aoverA*doverA)-(doverA)^2);
down=(aoverA*doverA+(doverA)^2);
k=up/down;
end

for aoverA=0:5:100
for doverA = 0:0.05:0.30
k=value(doverA,aoverA) %calling of function
plot([0; aoverA(:,1)], [0;doverA],'-ro')
hold on
endfor
endfor

title('Curve Plotting');
xlabel('a/A');
ylabel('d/A');

This code plotting below graph

But I want this graph . It means that it will take values from
(0.30,5,0.05,100)
