plotting non-linear equation

Hello matlab,

I have this equation y*x= 1+ ln(y/x);

x varies from 0 to 1. Is there any way to plot x vs y?

Best

There is, if you have the Symbolic Math Toolbox:

syms x y 
Eqn = y*x == 1 + log(y/x);
y = solve(Eqn, y);

figure(1)
fplot(real(y), [0 1], '-b')
hold on
fplot(imag(y), [0 1], '-r')
hold off
grid
set(gca, 'YScale','log')
xlabel('X')
ylabel('Y')
legend('Re\{y\}', 'Im\{y\}')

y =
-wrightOmega(- log(-1/x^2) - 1)/x
