function main
S = 1; c = -1.25; Pr = 0.7; n = 0.8;
% n=input('n=') %%n=-0.3,-0.5
x = [3 -1];
x1 = fsolve(@solver, x);
function F = solver(x)
[t, u] = ode45(@equation,[0,5], [S, c, x(1), 1, x(2)]);
F = [u(end, 2)-1 u(end, 4)];
figure(1)
plot(t, u(:,4), 'b-');
hold on
end
function dy = equation(t, y)
dy = zeros(5,1);
dy(1) = y(2);
dy(2) = y(3);
dy(3) = y(2)^2 - y(1) * y(3) - 1;
dy(4) = y(5);
dy(5) = Pr * (n * y(2) * y(4) - y(1) * y(5));
end
end
%%The present code gives multiple graphs instead of 1

Minati - by multiple graphs do you mean multiple figures or multpile plots?

Dear Geoff
- by multiple graphs do you mean multiple figures or multpile plots?
its multiple curves in one fig. but I need only one curve.
If I strike out "hold on" option then only one curve is comming.
But for different inputs of 'n'.,different curves should come into picture,which are not coming.

Move the plotting out of solver() and put it after the fsolve() call before the definition of the function solver.

how can we take 'c' in x-axis(continuous range.[-1.3:0.02:-1.1])
with this code.
still unable to draw
