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?

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